The invention provides a method for evaluating the peristalsis state of organs or tissues of a human body, which can evaluate the peristalsis state of the organs or tissues objectively by continuously transmitting ultrasonic waves to the peristalsis organs or tissues for a period of time and detecting echoes and calculating the displacement or movement speed of the organs or tissues at different times. The specific process will be described in detail below. Hereinafter, the description will be mainly given taking the measurement of the peristaltic parameters of the endometrium as an example. However, it will be appreciated by those skilled in the art that the present invention is not limited to endometrium, and that the methods and apparatus of the examples below are also applicable to measuring peristaltic parameters of other tissues, such as the intestine, stomach, etc. These peristaltic tissues, for which peristaltic parameter measurements are to be made, are referred to herein as "peristaltic targets".

The embodiment of the application provides a measuring method, a measuring device and a storage medium for an endometrium peristalsis parameter. The measuring method of the uterine endometrium peristalsis parameter can be applied to measuring equipment and is used for detecting the state information of endometrium or biological tissue, wherein the state information comprises displacement information, speed information, the amplitude of peristalsis or the frequency of the peristalsis and the like so as to accurately judge the peristalsis condition of the 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 structural block diagram of an apparatus for measuring an endometrial peristalsis parameter according to an embodiment of the present application. The measurement 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.

The transmit circuitry 16 may excite the probe 13 to transmit ultrasound waves into the endometrium. The reception circuit 17 may receive echoes of the ultrasonic waves returned from the endometrium by the probe 13, thereby obtaining echo signals. The echo signal is beam-synthesized by the beam synthesis 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 measuring 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 independent from the measuring apparatus 10, or may be a display screen on an electronic device such as a mobile phone, a tablet computer, or the like.

The Processor 11 may be a Central Processing Unit (CPU), and 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 the like. 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 method for measuring a uterine endometrial peristalsis 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.

The probe 13, under the control of the processor 11 through the transmission circuit 16, may transmit ultrasonic waves having different parameters, such as ultrasonic waves having different frequencies, intensities, and the like.

For example, after transmitting a first ultrasonic wave, adjusting the transmission parameters to transmit a second ultrasonic wave, wherein the first ultrasonic wave can be used for forming a B-mode ultrasonic image, and the second ultrasonic wave can be used for detecting the peristalsis parameters of the endometrium. Wherein the parameters of the first ultrasonic wave and the second ultrasonic wave may be different.

The probe 13 is controlled to emit ultrasonic waves toward the endometrium. The transmitted ultrasound beam has a transmission angle. Herein, an included angle between a propagation direction of the transmitted ultrasonic beam and a normal line of an array element arrangement plane or a curved surface of the probe is referred to as a transmission angle of the ultrasonic beam. When receiving the ultrasound echo, the reception may be performed according to the reception line (or reception beam), so as to obtain the echo data on the reception line. Herein, the included angle between the receiving line (or receiving beam) and the normal of the probe array element arrangement plane or curved surface is referred to as the receiving angle.

It should be noted that the transmission angle and the reception angle can also be understood as a transmission direction and a reception direction, and in the embodiments of the present application, the transmission angle and the reception angle are described. Of course, the transmission direction and the reception direction may be used for description.

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 angles 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.

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

In fig. 2, two probe array elements 130 are selected to form a transmit aperture 231, and the transmit aperture 231 is controlled to transmit ultrasound waves to the endometrium 20. Wherein the arrows indicate the propagation direction of the transmitted ultrasound beam. At this time, the propagation direction of the ultrasonic beam coincides with the normal direction of the array element arrangement plane, and therefore the transmission angle can be considered to be 0 degree.

Illustratively, as shown in fig. 3, the transmit aperture 331 and the transmit aperture 332 are respectively selected to be located at different positions, and both the transmit aperture 331 and the transmit aperture 332 transmit ultrasound waves to the endometrium 20, wherein the arrows represent the propagation directions of the transmitted ultrasound beams. It can be seen that the emission angles of the two are different.

It should be noted that the probe array element can be used for transmitting or receiving ultrasonic waves through the control of the transmission/reception selection switch 15. For example, the transmit aperture 331 and the transmit aperture 332 may also serve as receive apertures. Of course, different probe elements than transmit aperture 331 and transmit aperture 332 may be selected as receive apertures.

Illustratively, as shown in fig. 4, ultrasound waves are transmitted to the endometrium 20 through the transmitting aperture 431, and when receiving the echo of the ultrasound waves, the echo of the ultrasound waves transmitted by the transmitting aperture 431 can be received by a probe array element different from the transmitting aperture 431, such as the echo of the ultrasound waves received by the receiving aperture 432; the echo of the ultrasonic wave transmitted by the transmitting aperture 431 can be received by the receiving aperture.

In fig. 4, the dashed arrows represent the receive lines or beams. It can be seen that receive aperture 431 has a different corresponding receive angle than receive aperture 432.

It should be noted that the probe 13 is illustrated as a schematic cross-sectional view, and it is understood that the probe 13 has a three-dimensional structure, and in the case of an area-array probe, the probe includes a plurality of regularly arranged probe array elements 130 in both the longitudinal direction and the transverse direction on the probe surface. The above shows the arrangement of the probe array elements in only one direction.

It should be noted that in the embodiments of the present application, the endometrium may be the entire endometrium or a partial region of the endometrium, i.e. a region representing a local position of the endometrium. Where the endometrium 20 is represented as the entire endometrium, the endometrium 20 may include a plurality of local location areas that are local areas formed by the division of the endometrium.

The detailed description of the measuring method of the endometrial peristalsis parameters provided by the embodiment of the present application will be provided below with reference to the specific structure and working principle of the measuring device 10 and the probe 13.

Referring to fig. 5, fig. 5 is a schematic flow chart of a method for measuring an endometrial peristalsis parameter according to an embodiment of the present application. As shown in fig. 5, the method for measuring the endometrial peristalsis parameters specifically comprises steps S101 to S104.

And S101, transmitting ultrasonic waves to the endometrium.

The probe is controlled to emit ultrasound waves at a certain emission angle towards the endometrium, which here can be a part of the entire endometrium, but of course also the entire endometrium.

Illustratively, as shown in FIG. 6, the transmit aperture 631 of the control probe 13 transmits ultrasound waves to the endometrium 20.

In fig. 6, the solid line with arrows is the transmission line or the transmission beam. It can be seen that the propagation direction of the transmitted beam is parallel to the normal direction of the array element arrangement plane, so the transmission angle can be considered as alpha₁Is 0 degrees.

In one embodiment, the ultrasound is transmitted to the endometrium, although it may be transmitted at multiple transmit angles to improve the accuracy of the measurement of the peristaltic parameter.

S102, receiving the echoes of the ultrasonic waves at least two receiving angles to obtain at least two groups of echo signals.

Each group of echo signals corresponds to each receiving angle, namely, a group of echo signals corresponding to each receiving angle is obtained from each receiving angle. Each group of echo signals comprises signals at a plurality of different moments, namely echo signals acquired by a plurality of time acquisition points.

For example, as shown in FIG. 6, at an emission angle α through an emission aperture 631₁Emitting ultrasound waves into the endometrium, wherein the emission angle alpha₁Is 0 deg.. Through acceptance apertures 632 and 633, respectively, at an acceptance angle β₂And a reception angle beta₃And receiving the echo of the ultrasonic wave to obtain two groups of echo signals.

As another example, as shown in FIG. 7, at a transmit angle α through a transmit aperture 731₁Ultrasound is transmitted to the endometrium through transmit aperture 731 as the receive aperture, receive aperture 732 and receive aperture 733 at a receive angle β, respectively₁Angle of reception beta₂And a reception angle beta₃And receiving the echoes of the ultrasonic waves to obtain three groups of echo signals.

Note that the emission angle α₁The included angle formed by the emission wave beam and the normal direction of the array element arrangement plane and the receiving angle beta₁Angle of reception beta₂And a reception angle beta₃All are included angles formed by the receiving wave beams and the normal direction of the array element arrangement plane.

Of course, the echoes of the ultrasonic waves are received at a plurality of different reception angles, and a plurality of echo signals corresponding to the respective reception angles are obtained.

For each transmission of the ultrasound, the echo signals are received from different reception angles, and the transmission and reception process is continued for a period of time, as shown in fig. 8, for a plurality of different times (T)₁、T₂、T₃、T₄、T₅...) so that each set of echo signals includes signals at multiple time instants.

During each transmission, a part of probe array elements can transmit ultrasonic waves to the peristaltic tissue, ultrasonic echoes are returned to each probe array element after the ultrasonic echoes reach endometrium, receiving apertures of at least two different positions are determined, and returned ultrasonic echo signals are received by the receiving apertures respectively.

S103, calculating the peristalsis parameters of the endometrium in each direction of at least two directions corresponding to the at least two receiving angles according to the at least two groups of echo signals respectively, and obtaining the peristalsis parameters in the at least two directions.

Wherein the endometrial peristalsis parameters include a motion displacement component and/or a motion velocity component. And processing each group of echo signals at least two moments to obtain a motion displacement component and/or a motion velocity component corresponding to the group of echo signals. I.e. the motion displacement component and/or the motion velocity component of the endometrium in the direction of the reception angle corresponding to the set of echo signals.

For example, three sets of echo signals are obtained, and each set of echo signals obtains corresponding motion displacement components and/or motion velocity components, so that three motion displacement components and/or motion velocity components of the endometrium can be obtained.

In one embodiment, when determining the peristalsis parameter, the module matching algorithm may be used to calculate the peristalsis parameter of the endometrium in the direction corresponding to each group of echo signals according to each group of echo signals.

Specifically, when the motion displacement component is obtained, specifically, a module matching algorithm is used for calculating a peristalsis parameter of the endometrium according to the echo signals at least two moments in each group, wherein the peristalsis parameter is the motion displacement component.

Specifically, by using a Block-Matching algorithm (Block-Matching), for an echo signal at a certain target position at a certain time, searching different positions of the echo signal at another time, finding out a position with the maximum cross-correlation with the echo signal, and calculating the displacement of the endometrium according to the difference between the maximum position and the original position.

In another embodiment, a peristalsis parameter of the endometrium of interest, which is a motion velocity component, may be calculated from the echo signals at least two time instants in each group using the doppler effect.

Specifically, based on the ultrasonic doppler effect, the moving speed of a certain target position at each time is detected in a principle similar to that of conventional blood flow imaging. When the probe is not moved and the endometrium moves, the moving speed component of the endometrium can be quickly calculated by receiving the frequency of the echo of the ultrasonic wave sent to the endometrium and utilizing the ultrasonic Doppler effect according to the frequency of the echo, the propagation speed and the transmitting frequency of the ultrasonic wave.

It should be noted that, of course, the creep parameter may also be calculated in other manners, such as a displacement detection method based on signal autocorrelation or cross-correlation, and a motion displacement component is calculated according to each group of echo signals.

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

In one embodiment, the peristaltic parameter may also be other parameters reflecting the motion state related to the peristaltic displacement or peristaltic velocity calculated based on the peristaltic displacement or peristaltic velocity, such as at least one of tissue strain caused by peristaltic motion, tissue strain rate caused by peristaltic motion, acceleration of peristaltic motion, and the like. Further, in one embodiment, the peristaltic parameter may be a peristaltic displacement or a peristaltic velocity of a particular point, or the peristaltic parameter may be at least one statistic of the peristaltic displacement or the peristaltic velocity, such as a maximum peristaltic displacement, a minimum peristaltic displacement, a mean of the peristaltic displacements, a variance of the peristaltic displacements, a maximum peristaltic velocity, a minimum peristaltic velocity, a mean of the peristaltic velocities, a variance of the peristaltic velocities, or 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.

And S104, determining the state information of the endometrium according to the peristalsis parameter of the endometrium.

Wherein, the state information of the endometrium is determined according to a plurality of peristalsis parameters, the state information comprises information of displacement, speed, movement direction and/or amplitude, and the like, and one or more combinations of the displacement, the speed, the movement direction and/or the amplitude can be determined.

Specifically, synthesizing according to the motion displacement component and/or the motion speed component of the endometrium to determine the motion vector corresponding to the endometrium; and determining the corresponding state information of the endometrium according to the motion vector.

For example, the motion velocity components corresponding to three different receiving angles are synthesized, the synthesized quantity after vector synthesis is used as the motion vector corresponding to the endometrium, and the motion velocity magnitude and direction of the endometrium are determined according to the synthesized motion vector, and the motion velocity magnitude and direction are the state information of the endometrium.

For general ultrasonic detection, the positions, directions, and the like of ultrasonic wave transmission and reception are all fixed, and the directions of transmission and reception are the same. 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, so that the obtained detection result may have a large difference from the real motion vector, which further results in a low accuracy of the detected peristaltic parameter and an inaccurate state information.

In the embodiment of the application, the peristalsis parameters of a plurality of receiving angles are obtained through calculation, and the state information of the endometrium is determined according to the plurality of peristalsis parameters, so that the state information can be obtained to be closer to the vibration direction of the endometrium, and the accuracy of measuring the peristalsis parameters or the state information is improved.

In one embodiment, for observing the endometrium, the endometrium may be imaged based on the at least two sets of echo signals, resulting in an image of the tissue structure of the endometrium.

Specifically, the endometrium may be imaged according to one of at least two sets of echo signals, or the endometrium may be imaged according to a combination of multiple sets of echo signals, so as to obtain a tissue structure image of the endometrium.

The image of the tissue structure is an image, and the image may be, for example, a B image, commonly referred to as a B-mode ultrasound image. Of course, other types of images are possible, such as M-type images or color Doppler images.

After the tissue structure image of the endometrium is obtained, the tissue structure image can also be displayed for the user to observe in real time. Of course, the tissue structure image may be sent to the user or printed so that the user views the endometrium of interest.

In one embodiment, the endometrium is imaged, in particular by using a spatial compounding technique to image the endometrium according to at least two groups of echo signals, resulting in an image of the tissue structure of the endometrium. By compounding echo signals of different emission angles, a spatial compounding effect can be obtained, so that artifacts can be eliminated, and a clearer and finer image can be obtained.

In an embodiment, imaging the endometrium may specifically be used for imaging the endometrium from a set of echo signals resulting in an image of a tissue structure of the endometrium. Specifically, the imaging principle used for imaging the endometrium may be a principle of forming a B image from an echo signal, thereby improving the imaging efficiency of the tissue structure image. Wherein the image of the endometrium is obtained as a B-image, exemplarily shown as B-image 21 in fig. 9.

In one embodiment, after said determining of status information of the endometrium from a peristaltic parameter of the endometrium, the peristaltic parameter and/or the status information may also be displayed. In particular, the peristaltic displacement component and/or the peristaltic velocity component and/or the peristaltic strain component and/or the peristaltic acceleration component and/or the motion vector and/or the status information is displayed. So as to be convenient for the user to view.

Of course, the peristaltic parameter and/or status information may also be displayed on the image of the tissue structure of the endometrium. So that the user can also obtain the peristalsis parameter and the state information when observing the tissue structure image, and the use by the user is further facilitated.

In one embodiment, the ultrasound is emitted towards the endometrium, and may be emitted at a plurality of emission angles towards the endometrium. Accordingly, when receiving the echo of the ultrasonic wave, the echo of the ultrasonic wave transmitted at each of the transmission angles is received at least two reception angles.

At least two groups of echo signals can be obtained by transmitting ultrasonic waves at each transmitting angle, more groups of echo signals can be obtained by a plurality of transmitting angles, and therefore peristaltic parameters in more directions can be obtained, and the accuracy of the state information of the endometrium is further improved.

In one embodiment, ultrasound is emitted to the endometrium, specifically: alternately transmitting a first ultrasound wave and a second ultrasound wave to the endometrium of interest, the first ultrasound wave being used for imaging a tissue structure image of the endometrium, the second ultrasound wave being used for determining a peristaltic parameter of the endometrium.

As shown in fig. 10, the first ultrasonic wave is a B transmission frame, and the second ultrasonic wave is an a transmission frame, that is, the first ultrasonic wave and the second ultrasonic wave are alternately transmitted, specifically, the first ultrasonic wave may be transmitted first, and the second ultrasonic wave may be transmitted first.

It should be noted that the first ultrasonic wave transmission and reception are not limited, for example, the transmission angle and the reception angle may be the same, or a single angle may be used for reception.

It should be noted that the second ultrasound is used to determine the peristaltic parameters of the endometrium, so the transmitting and receiving mode in the above embodiment is needed, that is, the ultrasound is transmitted to the endometrium at a certain transmitting angle or a plurality of transmitting angles; and for each transmitting angle, receiving the echo of the ultrasonic wave at least two receiving angles to obtain at least two groups of echo signals, wherein each group of echo signals corresponds to each receiving angle.

The first ultrasonic wave and the second ultrasonic wave with different actions are alternately carried out, so that the change of the B image can be synchronously observed while the peristalsis parameter is detected. Because the detection time of the peristalsis parameters is long, the detection time may be tens of seconds or minutes, and at this time, if the user does not operate properly, such as the situation of probe displacement or poor contact, the situation can be found in time through the synchronous B image and adjusted in time.

The transmission/reception sequence of the first ultrasonic wave is independent of the transmission/reception of the second ultrasonic wave, and the parameter control is also independent.

It should be noted that for each instant of the second ultrasound, it is possible to include a plurality of shots for acquiring tissue signals at different locations or over a range of widths of the endometrium, respectively. However, the multiple sets of echo signals correspond to repetitions of the same target location at different times.

The alternating mode can lead to a longer time interval between two adjacent frames of creep wave detection which are transmitted and received repeatedly, so that the creep parameters at finer moments cannot be acquired. To improve the accuracy of the peristaltic parameters, interpolation may of course be performed in the time direction, obtaining echo signals at more time instants.

Specifically, before the echo signals at least two time instants in each group are processed, interpolation processing is performed on the echo signals of each group. And processing according to each group of echo signals after interpolation processing to obtain the peristalsis parameters of the interested endometrium. Thereby improving the accuracy of the resulting peristaltic parameters.

In one embodiment, the detection range can be narrowed to improve the detection efficiency of the peristaltic parameter, thereby emitting ultrasound waves to a region of interest in the endometrium. Specifically, transmitting an ultrasonic wave to an endometrium and receiving an echo of the ultrasonic wave; obtaining a tissue structure image of the endometrium according to the echo imaging of the ultrasonic wave, and determining an interested area according to the tissue structure image; and transmitting ultrasound waves to the region of interest. Therefore, the detection range is narrowed and the detection efficiency is improved by emitting ultrasonic waves to the interested region in the endometrium.

And determining an interested region according to the tissue structure image, displaying the tissue structure image of the endometrium, acquiring a frame selected by a user in the tissue structure image, and taking the region corresponding to the frame as the interested region. Therefore, the region of interest can be determined quickly, and the experience of the user is improved.

For example, as shown in fig. 11, the B image 21 is displayed on the display, and if the user selects an area of interest in the B image 21 and forms a frame, the frame selected by the user in the image is acquired and an area corresponding to the frame is used as the area of interest 210.

In the embodiments, at least two groups of echo signals corresponding to each receiving angle are obtained by receiving echoes of ultrasonic waves transmitted to the endometrium at least two receiving angles, and the peristalsis parameters corresponding to the endometrium are calculated according to each group of echo signals, so that the peristalsis parameters in multiple directions can be obtained; the state information of the endometrium is determined according to the peristalsis parameters corresponding to the multiple directions, so that the accuracy of detecting the peristalsis parameters or the state information of the endometrium can be improved.

Referring to fig. 12, fig. 12 is a schematic flow chart of another method for measuring a parameter of endometrial peristalsis according to an embodiment of the present application. As shown in fig. 12, the method for measuring the endometrial peristalsis parameters specifically includes steps S201 to S203.

The peristalsis parameters of the endometrium can be measured quickly by emitting at one emitting angle, and can be measured accurately by a plurality of emitting angles.

Specifically, the first emission mode and the second emission mode can be selected according to the user requirements, wherein the first emission mode corresponds to one emission angle, and the second emission mode corresponds to a plurality of emission angles. Before transmitting the ultrasonic waves to the endometrium, displaying a first transmission mode and a second transmission mode for a user to select, and determining to transmit the ultrasonic waves to the endometrium at a certain transmission angle or to transmit the ultrasonic waves to the endometrium at a plurality of transmission angles according to the selection of the user.

Regardless of whether the ultrasonic waves are transmitted at a certain transmission angle or at a plurality of transmission angles, the echoes of the ultrasonic waves are received at least two receiving angles to obtain at least two groups of echo signals, wherein each group of echo signals corresponds to each receiving angle. I.e. the echoes of the ultrasound waves transmitted at each transmit angle are received at least two receive angles.

It should be noted that the ultrasonic waves are transmitted at a plurality of transmission angles, and the echoes of the ultrasonic waves are received at least two reception angles for each transmission angle.

And processing the echo signals at least two moments in each group by adopting a module matching algorithm or Doppler effect processing and the like, so as to calculate corresponding motion components in different directions and obtain the peristalsis parameters of the endometrium according to a plurality of motion components.

In one embodiment, the echoes of the ultrasonic waves are received at least two receiving angles, and two receiving angles with larger difference can be selected to receive the echoes of the ultrasonic waves. Thereby avoiding that the motion components of both reception angles differ significantly from the true motion of the endometrium, resulting in a large measurement error. The accuracy of the measurement of the peristaltic parameter can thereby be further improved. The two receiving angles are different from each other, for example, are set to be larger than a preset angle.
