Technical Field

The application relates to the technical field of medical equipment, in particular to a detection method, detection equipment and a storage medium for a peristaltic parameter.

Background

The existing ultrasonic method for detecting the endometrial peristalsis mainly comprises the steps of performing transvaginal ultrasound, observing the change of a two-dimensional B-type image by a doctor continuously for a period of time in real time by naked eyes, or observing a stored B-type image video for a period of time by the doctor, capturing motion information of the endometrium, and judging the amplitude, frequency, direction and the like of a peristalsis wave.

The embodiment of the application provides a detection method and detection equipment for a peristaltic parameter and a storage medium. The detection method of the peristalsis parameter can be applied to a detection device and is used for detecting the peristalsis parameter of biological tissue, such as the peristalsis parameter of endometrium, wherein the peristalsis parameter comprises displacement information, speed information and the like so as to accurately judge the peristalsis condition of endometrium.

Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Referring to fig. 1, fig. 1 is a schematic block diagram illustrating a structure of a device for detecting a creep parameter according to an embodiment of the present application. The detection device 10 may include a processor 11, a memory 12, a probe 13, a display 14, a transmit/receive selection switch 15, transmit circuitry 16, receive circuitry 17, and beam forming circuitry 18.

Wherein, the transmitting circuit 16 can excite the probe 13 to transmit ultrasonic waves to the endometrium; the receiving circuit 17 may receive an echo of the ultrasonic wave returned from the endometrium by the probe 13, thereby obtaining an echo signal; the echo signal is processed by the beam forming circuit 18 and then sent to the processor 11. The processor 11 processes the echo signals to obtain a peristaltic parameter of the endometrium, such as displacement or velocity. The peristaltic parameters obtained by the processor 11 may be stored in the memory 12 for display on the display 14.

In one embodiment, the display 14 of the detection apparatus 10 may be a touch display screen, a liquid crystal display screen, an OLED display screen, or the like, or may be a liquid crystal display, a television, or a separate display device that is independent from the detection apparatus 10, or may be a display screen on an electronic device such as a mobile phone, a tablet computer, or the like.

In practical applications, the Processor 11 may be a Central Processing Unit (CPU), and the Processor may also be other general purpose processors, Digital Signal Processors (DSP), Application Specific Integrated Circuits (ASIC), Field Programmable Gate Arrays (FPGA) or other Programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, and so on. Wherein the general purpose processor may be a microprocessor or the processor may be any conventional processor or the like, such that the processor 11 may perform the respective steps of the detection method of the peristaltic parameter in the various embodiments of the present application.

The Memory 12 may be a volatile Memory (volatile Memory), such as a Random Access Memory (RAM); or a non-volatile Memory (non-volatile Memory), such as a Read Only Memory (ROM), a flash Memory (flash Memory), a Hard Disk (Hard Disk Drive, HDD) or a Solid-State Drive (SSD); or a combination of the above types of memories and provides instructions and data to the processor.

Wherein the probe 13 can transmit ultrasonic waves with different parameters, such as different frequencies and intensities, etc., under the control of the processor 11 through the transmitting circuit 16.

The probe 13 includes a plurality of types of probes, such as a convex probe or a linear probe, and the control modes corresponding to the emission directions of the different types of probes for emitting the ultrasonic waves to the endometrium are different, for example, a mode of mechanically rotating the probe or a mode of electronically selecting different probe array elements can be adopted. The control mode of the receiving direction is the same as the control mode of the transmitting direction.

For example, as shown in fig. 2, the probe 13 includes a plurality of probe elements 130, and the probe elements 130 are used for transmitting and receiving ultrasonic waves, and specifically, whether to transmit ultrasonic waves or receive ultrasonic waves, can be determined by the processor 11 through the selection control of the transmit/receive selection switch 15. More specifically, one probe array element 130 may be selected to transmit ultrasound waves to the endometrium 20, and a plurality of probe array elements 130 may be selected to constitute a subset of the transmit array elements to transmit ultrasound waves to the endometrium 20.

For example, in fig. 2, four probe array elements 130 are selected to form a transmitting array element subset 131, and the transmitting array element subset 131 is controlled to transmit ultrasonic waves to the endometrium 20, wherein the transmitting direction of the transmitting array element subset 131 to transmit the ultrasonic waves to the endometrium 20 is the transmitting direction, i.e. the transmitting direction D1.

For example, in fig. 3, four probe array elements 130 at different positions are respectively selected to form a transmitting array element subset 131 and a transmitting array element subset 132, and the transmitting array element subset 131 and the transmitting array element subset 132 both transmit ultrasound waves to the endometrium 20, but the corresponding transmitting directions are different, and correspond to the transmitting direction D1 and the transmitting direction D2, respectively.

It should be noted that, through the control of the transmit/receive selection switch 15, the transmit array element subset 131 and the transmit array element subset 132 can also be used as the receive array element subset. Of course, other different numbers or different positions of probe elements 130 may be selected to form the transmit element subset, such as two or three probe elements.

In some embodiments, for better reception of the ultrasound waves returned from the endometrium 20, the transmission direction and the reception direction may be the same, i.e. the same number of probe elements 130 in the transmission element subset and the reception element subset and the positions of the plurality of probe elements 130 in the probe 13 may be selected to constitute the transmission element subset and the reception element subset by the same probe elements 130. For example, the transmit subset of elements 131 is used to transmit ultrasound and the echoes of the ultrasound are also received as a subset of receive elements.

It should be noted that, in the embodiment of the present application, the endometrium 20 may be the entire endometrium, or may be a partial region of the endometrium, that is, a local position region representing the endometrium, and the endometrium 20 may include a plurality of local position regions, which are local regions formed by dividing the endometrium.

The following describes in detail the detection method of the peristaltic parameter provided by the embodiment of the present application with reference to the specific structure and operation principle of the detection device 10 and the probe 13.

Referring to fig. 4, fig. 4 is a schematic flowchart of a method for detecting a peristaltic parameter according to an embodiment of the present application. As shown in fig. 4, the method for detecting the creep parameter specifically includes steps S101 to S106.

S101, emitting first ultrasonic waves to endometrium and receiving echoes of the first ultrasonic waves to obtain ultrasonic echo signals of the first ultrasonic waves.

Specifically, the probe is controlled to emit first ultrasonic waves to the endometrium and receive echoes of the first ultrasonic waves, and ultrasonic echo signals of the first ultrasonic waves are obtained. The first ultrasonic wave may be an ultrasonic wave for imaging an endometrium, such as a corresponding ultrasonic wave of a B-mode ultrasonic image, a C-mode ultrasonic image, an M-mode ultrasonic image, and the like.

The first ultrasonic wave and the second ultrasonic wave may be ultrasonic waves with the same parameters, or ultrasonic waves with different parameters, for example, the parameters of the first ultrasonic wave and the second ultrasonic wave are different by changing the transmitting frequency or the operating voltage of the probe. The first ultrasonic wave and the second ultrasonic wave may be transmitted in the same or different manners, for example, the first ultrasonic wave is transmitted in a diverging wave manner, and the second ultrasonic wave is transmitted in a focusing wave manner.

S102, obtaining an ultrasonic image of the endometrium according to the ultrasonic echo signal of the first ultrasonic wave.

Specifically, the endometrium is imaged according to the echo of the first ultrasonic wave, an ultrasonic image of the endometrium is obtained, and for example, the ultrasonic image of the endometrium can be a B image. In other embodiments, other types of images, such as an M-type image or a C-type image, may be used, and are not limited herein.

After obtaining the ultrasound image of the endometrium, the ultrasound image may be displayed by a display of a detection device. Therefore, the detection process of the peristalsis parameters can be observed by the user through the ultrasonic image, because the endometrial motion detection time is long (such as dozens of seconds or minutes), at the moment, if the user does not operate properly, the probe is displaced, or the contact is poor, and the like, the situation can be found in time and adjusted in time through the synchronous ultrasonic image.

S103, determining an interested area according to the ultrasonic image.

The region of interest is determined according to the ultrasound image of the endometrium, and specifically, the ultrasound image may be identified to determine the region of interest, for example, feature structures of the ultrasound image are identified, and a region containing a certain feature structure or some feature structures is determined as the region of interest. Alternatively, the ultrasound image is displayed and a region of interest is selected on the ultrasound image by the user.

Illustratively, by acquiring the region of interest selected by the user on the ultrasound image, the corresponding specific process is as follows: displaying the ultrasonic image of the endometrium, acquiring a frame selected by a user in the ultrasonic image, and taking an area corresponding to the frame as an interested area. The region of interest can be determined quickly, and the user experience can be improved.

For example, as shown in fig. 5, the ultrasound B image 21 is displayed on the display, and if the user selects an interested region in the ultrasound B image 21 and forms a border, the border selected by the user in the ultrasound image is obtained and a region corresponding to the border is used as the interested region 210.

And S104, transmitting second ultrasonic waves to the region of interest in at least two transmitting directions, and receiving echoes of the second ultrasonic waves to obtain at least two groups of echo signals.

Wherein each set of echo signals corresponds to each of the transmit directions and comprises echo signals at least two time instants. Namely, each transmitting direction obtains a group of echo signals, and each group of echo signals comprises echo signals under a plurality of moments.

Specifically, the probe is controlled to transmit second ultrasonic waves to the endometrium in at least two transmitting directions, and the probe is controlled to receive echoes of the second ultrasonic waves to obtain at least two groups of echo signals. The direction of receiving the echo of the second ultrasonic wave may be the same direction as the direction of transmitting the second ultrasonic wave, may be different from the direction of transmitting the second ultrasonic wave, or may be a plurality of receiving directions to receive the echo of the second ultrasonic wave in the same transmitting direction.

In one embodiment, the second ultrasonic wave may be transmitted to the region of interest in at least two transmitting directions, and the echo of the second ultrasonic wave is received in the same receiving direction as the transmitting direction, so as to obtain at least two sets of echo signals, that is, the direction of receiving the echo of the second ultrasonic wave is the same as the direction of transmitting the second ultrasonic wave. The receiving direction is the same as the transmitting direction, and includes two directions that are completely the same or two directions that are substantially the same, where completely the same refers to two parallel directions, and substantially the same refers to the receiving direction and the transmitting direction that are not completely parallel but have a certain relative inclination angle, but the inclination angle needs to be within a preset range, for example, within 5 ° or within 10 °, and both directions can be considered to be substantially the same.

For example, as shown in fig. 6, the transmitting array element subset 131 and the transmitting array element subset 132 of the probe 13 are controlled to transmit the second ultrasonic wave to the endometrium 20 in the transmitting direction D1 and the transmitting direction D2, respectively, and the transmitting array element subset 131 and the transmitting array element subset 132 of the probe 13 are controlled as the receiving array element subset to receive the echo of the second ultrasonic wave in the receiving direction D1 'and the receiving direction D2'. The emitting direction D1 and the receiving direction D1 'are in the same direction, and the emitting direction D2 and the receiving direction D2' are in the same direction.

For example, as shown in fig. 7, the emitting direction D1 and the receiving direction D1 ', and the emitting direction D2 and the receiving direction D2' are not completely parallel, but are inclined at an angle. In particular, the subset of receiving elements 131 ', 132' may select different probe elements 130 than the subset of transmitting elements 131, 132, resulting in the transmit direction being substantially the same as the receive direction.

In some embodiments, transmitting the second ultrasound waves to the endometrium in at least two transmit directions may include transmitting the second ultrasound waves to the endometrium in three or more transmit directions, and as shown in fig. 8, each of the four probe array elements 130 is selected to constitute a transmit array element subset 131, a transmit array element subset 132, and a transmit array element subset 133, and the second ultrasound waves are transmitted in the transmit direction D1, the transmit direction D2, and the transmit direction D3, and echoes of the second ultrasound waves are received in the receive direction D1 ', the receive direction D2 ', and the receive direction D3 '. Of course, more transmitting directions may be selected for transmitting, different transmitting directions may not be on the same plane, and for the second ultrasonic waves transmitted in each transmitting direction, the echoes of the second ultrasonic waves may be received in the receiving direction in the same direction as the transmitting direction to obtain at least two sets of echo signals.

The method comprises the following steps of transmitting second ultrasonic waves to endometrium in at least two transmitting directions, receiving echoes of the second ultrasonic waves to obtain at least two groups of echo signals, wherein the corresponding transmitting and receiving modes of the ultrasonic waves at least comprise two modes, which are respectively: the first transmitting and receiving mode and the second transmitting and receiving mode.

The first transmission and reception mode is as follows:

the transmitting and receiving mode is to change the transmitting direction to transmit and receive the second ultrasonic wave to the endometrium, and specifically comprises the following steps: transmitting a second ultrasonic wave to the endometrium in a transmitting direction and receiving an echo of the second ultrasonic wave; changing the emission direction to emit the second ultrasonic waves to the endometrium in the changed emission direction and receiving the echo of the second ultrasonic waves after changing the emission direction; and repeating the process of transmitting a second ultrasonic wave in one transmitting direction and receiving the echo of the second ultrasonic wave, and changing the transmitting direction to transmit the second ultrasonic wave in the changed transmitting direction and receive the echo of the second ultrasonic wave to obtain at least two groups of echo signals, wherein each group of echo signals corresponds to each transmitting direction at different moments.

As shown in fig. 9, at time T1, a second ultrasonic wave is first transmitted to the endometrium in the transmitting direction D1 and the echo of the second ultrasonic wave is received in the receiving direction D1' which is the same as the transmitting direction D1; at time T2, the transmit direction D1 is changed to the transmit direction D2, the second ultrasound is transmitted to the endometrium in the transmit direction D2 and the echo of the second ultrasound is received in the receive direction D2' co-directional with the transmit direction D2. At time T3, transmitting a second ultrasonic wave in the transmitting direction D1 and receiving an echo of the second ultrasonic wave; at a time T4, changing the transmission direction and transmitting the second ultrasonic wave in the transmission direction D2 and receiving the echo of the second ultrasonic wave; and continuously repeating the sending and receiving processes to obtain echoes at a plurality of moments so as to obtain two groups of echo signals. I.e. T1, T3.. the corresponding echoes constitute one set of echo signals corresponding to the transmit direction D1, and T2, T4.. the corresponding echoes constitute another set of echo signals corresponding to the transmit direction D2.

It should be noted that, if the above-mentioned three or four transmitting directions are included, three or four sets of echo signals corresponding to the three or four transmitting directions will be obtained finally, and more sets of echo signals corresponding to more transmitting directions will be obtained.

In one embodiment, the second ultrasound waves are emitted towards the endometrium in at least two emission directions, wherein the second ultrasound waves comprise focused waves, plane waves, divergent waves or weakly focused waves. The coverage of the area to be detected of the endometrium can be improved.

Specifically, in order to effectively cover all the regions to be detected of the endometrium, ultrasonic emission is performed in a plane wave emission manner, a divergent wave emission manner, or a weakly focused emission manner. At the moment, all echo signals of the whole area to be detected can be recovered only by one-time transmission.

In one embodiment, the region of interest of the endometrium comprises a plurality of local position areas, as shown in fig. 10, such as three local position areas, local position area S1, local position area S2 and local position area S3.

Correspondingly, transmitting a second ultrasonic wave to the region of interest in one transmitting direction and receiving an echo of the second ultrasonic wave comprises: transmitting second ultrasonic waves to each local position area of the interested area in one transmitting direction and receiving echoes of the second ultrasonic waves; transmitting the second ultrasonic wave to the region of interest in the changed transmission direction, and receiving an echo of the second ultrasonic wave in the changed transmission direction, including: and transmitting the second ultrasonic waves to each local position area of the region of interest in the changed transmitting direction, and receiving echoes of the second ultrasonic waves in the changed transmitting direction. And receiving the echo of the received second ultrasonic wave to obtain at least two groups of echo signals, wherein each group of echo signals corresponds to each transmitting direction and local area and comprises echo signals at least two moments.

Taking the reception of the second ultrasonic echo in the same reception direction as the transmission direction as an example, as shown in fig. 10, at time T1, first, the second ultrasonic wave is transmitted to three local position areas (S1, S2, and S3) of the region of interest in the transmission direction D1 and the echo of the second ultrasonic wave is received in the reception direction D1' in the same direction as the transmission direction D1; at time T2, the transmission direction D1 is changed to the transmission direction D2, the second ultrasonic wave is transmitted to three local position areas (S1, S2, and S3) of the endometrium in the transmission direction D2 and the echo of the second ultrasonic wave is received in the reception direction D2' which is the same direction as the transmission direction D2. At time T3, transmitting a second ultrasonic wave in the transmitting direction D1 and receiving an echo of the second ultrasonic wave; at time T4, transmitting a second ultrasonic wave in the transmitting direction D2 and receiving an echo of the second ultrasonic wave; the above sending and receiving processes are continuously repeated to obtain echoes at a plurality of times, and then two groups of echo signals at the local position S1, that is, one group of echo signals in the direction of T1 and T3.. time D1 'at the local position region S1, and another group of echo signals in the directions of T2 and T4.. time D2' at the local position region S1 are obtained. Similarly, two sets of echo signals in the local position region S2 and the local position region S3 can be obtained, and two sets of echo signals in the entire region of interest can be obtained by integrating the two sets of echo signals in the local position region S1, the local position region S2, and the local position region S3.

And a second transmitting and receiving mode:

the region of interest includes a plurality of local location regions. The transmitting and receiving mode is to transmit and receive ultrasonic waves to the region of interest in a mode of changing a local position region, and specifically comprises the following steps: respectively transmitting second ultrasonic waves to a local position area of the region of interest in at least two transmitting directions and receiving echoes of the second ultrasonic waves; changing the local position area, respectively transmitting ultrasonic waves to the changed local position area in at least two transmitting directions, and receiving echoes of second ultrasonic waves of which the local position area is changed; and repeating the process of transmitting the second ultrasonic wave to one local position area, receiving the echo of the second ultrasonic wave, changing the local position area, transmitting the second ultrasonic wave to the changed local position area and receiving the echo of the second ultrasonic wave after the local position area is changed until the second ultrasonic wave is transmitted to a plurality of local position areas to obtain at least two groups of echo signals, wherein each group of echo signals corresponds to each transmitting direction and local area and comprises echo signals at least two moments.

Taking the example of receiving the second ultrasonic echo in the same receiving direction as the transmitting direction, as shown in fig. 11, it is assumed that the region of interest includes two local position regions, i.e., a local position region S1 and a local position region S2. At time T1, a second ultrasonic wave is transmitted to the local position region S1 in three transmission directions D1, D2, and D3, respectively, and echoes of the second ultrasonic wave are received in reception directions D1 ', D2 ', and D3 ' that are in the same direction as the transmission directions D1, D2, and D3; changing the local position area S1 to the local position area S2, transmitting a second ultrasonic wave to the local position area S2 in three transmission directions D1, D2 and D3, respectively, and receiving echoes of the second ultrasonic wave in reception directions D1 ', D2 ' and D3 ' which are in the same direction as the transmission directions D1, D2 and D3 at time T2; the above process is repeated until the second ultrasonic wave is transmitted to a plurality of local position areas, that is, the process of transmitting the second ultrasonic wave to the local position area S1 and receiving the echo of the second ultrasonic wave and changing to the local position area S2 is repeated in the same manner at the time T3, and the process of transmitting the second ultrasonic wave to the local position area S2 and receiving the echo of the second ultrasonic wave are repeated at the time T4, so that at least three sets of echo signals of each local position area are obtained, and each set of echo signals includes echo signals of at least two times. For the local location region S1, the first set of echo signals includes echoes in the D1 ' direction at times T1, T3.. the second set of echo signals includes echoes in the D2 ' direction at times T1, T3.. the time, and the third echo signals includes echoes in the D3 ' direction at times T1, T3.. the time. Similarly, at least three sets of echo signals of the local position region S2 can be obtained, and at least three sets of echo signals of the entire region of interest can be obtained by integrating at least three sets of echo signals of the local position region S1 and the local position region S2.

It should be noted that the local position area may be a position area obtained by dividing the region of interest according to a user, so the region of interest may certainly include more local position areas, and the plurality of local position areas may have an arrangement order, for example, be arranged in rows or columns, so that the ultrasonic waves may be sequentially transmitted to the plurality of local position areas according to the arrangement order, for example, be transmitted in a row arrangement manner or be transmitted in a column arrangement manner, thereby shortening the transmission time and improving the transmission efficiency. The local position areas can also be automatically defined by the system, the number of the defined local position areas can be determined according to the size of the interested area, and the plurality of local position areas can have an arrangement order.

For the case that the region of interest includes a plurality of local position areas, if the number of the local position areas is too large for the first transmission and reception mode, it may cause a large transmission detection time interval in the same direction for any one local position area, which results in a long time interval between echoes of the second ultrasonic wave in the same transmission direction based on the same local position area, and a large calculation error of the peristaltic motion component in the transmission direction for the local position, which results in a certain distortion in the final calculation result of the peristaltic parameter.

In one embodiment, to improve the accuracy of the peristaltic parameters, step S101 further includes: acquiring the number of local position areas of an interested area, and selecting the transmitting and receiving mode to transmit and receive ultrasonic waves for each local position area of the interested area to obtain at least two groups of echo signals if the number of the local position areas of the interested area is larger than the number of preset areas; or a transmitting and receiving mode is adopted together with a transmitting mode of focused waves, plane waves, divergent waves or weak focused waves. By switching the transmitting and receiving modes, the detection efficiency of the peristaltic parameters is improved.

S105, calculating the peristaltic motion component of the endometrium in the region of interest in the emission direction corresponding to the group of echo signals according to each group of echo signals, and thus obtaining at least two peristaltic motion components.

Specifically, a peristaltic movement component of the endometrium in the region of interest can be calculated from each set of echo signals, and two sets of echo signals, two peristaltic movement components can be obtained, wherein each peristaltic movement component corresponds to the emission direction corresponding to each set of echo signals. Wherein the peristaltic motion component may be a displacement or a velocity.

For example, as shown in fig. 9, two sets of echo signals are obtained, one set is echo signals corresponding to T1 and T3. Therefore, a peristaltic motion component can be calculated according to a group of echo signals corresponding to the T1 and the T3 at two moments, wherein the group of echo signals corresponds to the emission direction D1, and the peristaltic motion component is a peristaltic motion component in the direction D1; and calculating another peristaltic motion component from a set of echo signals corresponding to the two time instants T2 and T4, the set of echo signals corresponding to the emission direction D2, the peristaltic motion component being the peristaltic motion component in the direction D2, whereby at least two peristaltic motion components can be obtained.

Illustratively, as shown in fig. 10, a plurality of local position areas such as a local position area S1, a local position area S2 and a local position area S3 can be obtained, and at least two sets of echo signals corresponding to each local position area can be obtained by transmitting a second ultrasonic wave to each local position area of the region of interest in one transmission direction and receiving an ultrasonic echo, changing the transmission direction, transmitting the second ultrasonic wave to each local position area of the region of interest in the changed transmission direction and receiving an echo of the second ultrasonic wave in the changed transmission direction, and repeating the above process. At least two peristaltic motion components corresponding to the local position area can be obtained according to at least two groups of second ultrasonic echo signals, for example, a peristaltic motion component in the direction of D1 of the local position area S1 is calculated according to echo signals corresponding to two moments of T1 and T3 in one group of echo signals with the emission direction of D1 in the local position area S1, and a peristaltic motion component in the direction of D2 of the local position area S1 is calculated according to echo signals corresponding to two moments of T2 and T4 in the other group of echo signals with the emission direction of D2 in the local position area S1.

Exemplarily, as shown in fig. 11, a second ultrasonic wave is transmitted to one local position region of the region of interest in at least two transmission directions, and an echo of the second ultrasonic wave is received; and changing the local position area, respectively transmitting second ultrasonic waves to the changed local position area in at least two transmitting directions, receiving the echo of the second ultrasonic waves after the local position area is changed, and repeating the process to obtain at least two groups of echo signals corresponding to each local position area. As shown in fig. 11, at least three sets of echo signals may be obtained, that is, a first set of echo signals includes echoes in the direction of D1 ' at the time of T1, T2, T3, and T4.. times of the local position region S1, a second set of echo signals includes echoes in the direction of D2 ' at the time of T1, T2, T3, and T4.. times of the local position region S1, and a third set of echo signals includes echoes in the direction of D3 ' at the time of T1, T2, T3, and T4.. times of the local position region S1. Therefore, at least two echo signals at the time can be selected from each group of the local position area S1 to calculate the corresponding peristaltic motion component of the group, so that the corresponding peristaltic motion components of the local position area S1 in the three transmitting directions of D1, D2 and D3 can be obtained. Similarly, it can be obtained that the peristaltic motion components of the local position region S2 in the three emission directions D1, D2 and D3 correspond to each other, and the peristaltic motion components in the local position region S1 and the local position region S2 are combined to obtain the peristaltic motion component of the entire region of interest.

For a certain target in space, such as endometrium, ultrasonic waves are transmitted for a period of time, and echoes of the ultrasonic waves are received, if the target position is moving, peristaltic displacement or peristaltic speed of the endometrium can be detected according to the echoes of the ultrasonic waves obtained at different moments based on a peristaltic detection method, and the displacement and the speed can be converted by d-v-t.

In one embodiment, a peristaltic movement component of the endometrium in the region of interest in the emission direction corresponding to each group of echo signals is calculated from each group of echo signals, the corresponding calculation method comprises: and calculating a peristaltic motion component of the endometrium in the region of interest in the transmitting direction corresponding to the group of echo signals according to each group of echo signals based on a module matching algorithm.

Illustratively, by using a Block-Matching algorithm (Block-Matching), for an echo signal at a target position at a certain time, the target position is a local position in the region of interest, a search is performed at different positions of the echo signal at another time, a position with the maximum cross-correlation with the target position is found, and a peristaltic displacement of the region of interest can be calculated according to the difference between the maximum position and the original position, where the peristaltic displacement is a peristaltic motion component.

In one embodiment, a peristaltic movement component of the endometrium in the region of interest in the emission direction corresponding to each group of echo signals is calculated from each group of echo signals, the corresponding calculation method comprises: based on the Doppler method, a peristaltic motion component of the endometrium in the interested area in the transmitting direction corresponding to the echo signals of each group is calculated according to the echo signals of each group.

Specifically, the movement speed of a certain target position at each moment is detected based on the ultrasonic doppler effect, the peristaltic speed of the region of interest can be calculated by receiving the frequency of the echo of the ultrasonic wave sent to the region of interest and utilizing the ultrasonic doppler effect according to the frequency of the echo, the propagation speed and the emission frequency of the ultrasonic wave, and the peristaltic speed is a peristaltic movement component.

And S106, determining the peristalsis parameters of the endometrium according to the at least two peristalsis motion components.

Wherein, the peristalsis parameter of the endometrium is determined according to the plurality of peristalsis motion components, and the peristalsis parameter is used for describing the motion state of the peristalsis of the endometrium. Specifically, synthesizing a plurality of peristaltic motion components to determine a corresponding motion vector of the endometrium; and determining the corresponding peristalsis parameter of the endometrium according to the motion vector.

Illustratively, taking the determination of the peristaltic velocity vector by the peristaltic velocity component as an example, as shown in fig. 14, the component velocity of the point M in the direction D1 is V1, the component velocity in the direction D2 is V2, a first reference line L1 perpendicular to the direction D1 can be determined based on the velocity component V1, a second reference line L2 perpendicular to the direction D2 can be determined based on the velocity component V2, and the peristaltic velocity vector V of the target point can be determined by connecting the target point M with the intersection point O of the first reference line L1 and the second reference line L2.

For another example, the peristaltic motion components in three different directions may be synthesized to obtain the motion vector of the peristaltic motion, for example, the component velocities in three different directions are synthesized into a vector velocity in a three-dimensional space. The number of motion components of the motion vector that synthesizes the peristaltic motion is not limited. Further, the peristalsis parameter may be determined by a motion vector of the peristalsis motion, and the peristalsis parameter may be the motion vector itself, or may be a quantitative or qualitative parameter describing the endometrium peristalsis further derived based on the peristalsis parameter.

In one embodiment, the creep parameter includes at least one statistic of the creep motion component or of a motion vector synthesized from the creep motion component, one of which may also be used to characterize the creep parameter.

In one embodiment, the peristalsis parameter may include at least one of amplitude of peristalsis, frequency of peristalsis, total significant peristalsis motion time within a preset time period, propagation direction of peristalsis motion, propagation speed of peristalsis motion, range of peristalsis motion, and the like.

In one embodiment, the peristaltic parameter may be other parameters reflecting the motion state, such as at least one of tissue strain caused by peristalsis, tissue strain rate caused by peristalsis, acceleration of peristaltic motion, and the like, which are calculated based on the peristaltic displacement or the peristaltic speed. Further, in one embodiment, the peristaltic parameter may also be at least one statistic of peristaltic displacement or peristaltic velocity, such as maximum peristaltic displacement, minimum peristaltic displacement, mean of peristaltic displacement, variance of peristaltic displacement, maximum peristaltic velocity, minimum peristaltic velocity, mean of peristaltic velocity, variance of peristaltic velocity, and the like.

The peristalsis is usually regular, periodic and propagates from a certain starting point of the endometrium to other positions, similar to the propagation of a vibration wave, so it is also common in the art to describe the peristalsis by a peristalsis wave, and the specific peristalsis parameter may be a parameter similar to a wave. The creep parameter can be calculated for a preset length of time. The preset period of time may be selected to be the period of primary clinical attention of the physician, such as 1 minute or 30 seconds, but is typically selected to be greater than or equal to the period of peristalsis to ensure that at least one complete peristalsis is detected.

In some clinical situations, the peristalsis may also be irregular or disorganized. Therefore, the above-mentioned peristalsis parameters may also be a degree of disorder of peristalsis movement, a degree of unevenness of peristalsis amplitude, a degree of unevenness of peristalsis direction, and a distribution of peristalsis movement in endometrium, etc. parameters reflecting an irregular or disordered state of peristalsis movement.

For general ultrasonic detection, the positions, directions, etc. of ultrasonic wave transmission and reception are all fixed singly. Therefore, the displacement data (or velocity data) calculated from the echo signal of the acquired ultrasonic wave mainly reflects the motion information of the current direction (detection direction). However, in practice, the real tissue motion direction may be different from the detection direction, and therefore, the obtained detection result may have a larger difference from the real motion vector, which in turn results in a lower accuracy of the detected peristalsis parameter. In the embodiment of the application, peristaltic motion components of a plurality of detection directions are obtained through calculation, and the peristaltic parameters of the endometrium are determined according to the peristaltic motion components, so that the accuracy rate of the peristaltic parameters is improved.

It should be noted that, in one embodiment, the first ultrasonic wave and the second ultrasonic wave are emitted alternately. Specifically, the probe is controlled to alternately transmit a first ultrasonic wave and a second ultrasonic wave to the endometrium, wherein the second ultrasonic wave is transmitted to the endometrium by adopting at least two transmitting directions, and the transmitting direction of the first ultrasonic wave is not limited.

Illustratively, as shown in fig. 12, a first ultrasonic wave B is emitted to the endometrium, a second ultrasonic wave a is emitted to the endometrium at the time T1, the first ultrasonic wave B is emitted to the endometrium, and the second ultrasonic wave a is emitted to the endometrium at the time T2, and the steps are cycled until the set detection time is finished. Of course, the second ultrasonic wave a may be emitted to the endometrium first, and then the first ultrasonic wave B may be emitted to the endometrium first, as long as the ultrasonic waves are emitted alternately. In another embodiment, the first ultrasonic wave may be transmitted by being inserted in the second ultrasonic wave, or the second ultrasonic wave may also be transmitted by being inserted in the first ultrasonic wave, as long as the received echo signal of the first ultrasonic wave can completely perform ultrasound image imaging, and the echo signals of at least two groups of second ultrasonic waves can be received, and the specific alternate transmission form is not limited.

The peristalsis parameter detection method disclosed in the above embodiment determines an interested area in an endometrium by using a first ultrasonic wave, transmits the ultrasonic wave to the interested area in at least two transmission directions, and receives the echo of the ultrasonic wave to obtain at least two groups of echo signals; calculating the peristaltic motion component of the endometrium in the region of interest in the transmitting direction corresponding to the group of echo signals according to each group of echo signals, and further obtaining the peristaltic motion component in multiple directions; the peristalsis parameters of the endometrium are determined according to the peristalsis motion components corresponding to the multiple directions, so that the accuracy of the peristalsis parameters can be improved.

In some embodiments, reference may be made to the method for detecting the peristalsis parameter of the endometrium in the above embodiments, and the peristalsis parameter of other peristalsis targets, such as the intestinal tract, the stomach or other tissues, may also be detected.

Illustratively, embodiments of the present application also provide another detection method of a peristaltic parameter, the detection method including:

transmitting a first ultrasonic wave to a peristaltic target and receiving an echo of the first ultrasonic wave to obtain an ultrasonic echo signal of the first ultrasonic wave; obtaining an ultrasonic image of the peristaltic target according to an ultrasonic echo signal of the first ultrasonic wave; determining an area of interest according to the ultrasonic image; transmitting second ultrasonic waves to the region of interest in at least two transmitting directions, and receiving echoes of the second ultrasonic waves to obtain at least two groups of echo signals, wherein each group of echo signals corresponds to each transmitting direction and at least comprises echo signals at two moments; calculating a peristaltic motion component of a peristaltic target in the region of interest in the transmitting direction corresponding to each group of echo signals according to each group of echo signals, thereby obtaining at least two peristaltic motion components; a peristaltic parameter of the peristaltic object is determined based on the at least two peristaltic motion components.
