Technical Field

The present application relates to the field of medical devices, and in particular, to a hip joint imaging method and a hip joint imaging system.

Background

Ultrasound imaging is widely used for analysis of various diseases, and can be used for carrying out ultrasound imaging on the hip joint so as to analyze the characteristics of the hip joint to determine the health state of the hip joint.

For example, developmental dysplasia of the hip (DDH) is the most common disease of the hip in children, which is a general term for a series of hip abnormalities that exist at birth or develop after birth in infants: including stable hip joint with dysplasia, subluxation of hip joint, complete dislocation of hip joint, reduction, complete dislocation and no reduction. The currently accepted therapeutic principle for DDH is early discovery, early treatment. The earlier the treatment, the simpler the treatment method and the better the treatment effect. Neonatal DDH screening is therefore of particular importance. Ultrasound imaging is the most common and useful imaging diagnostic method for early stage DDH. The advantages include: (1) the hip joints of the newborn and the infant are mainly composed of cartilages, the femoral heads are not ossified, the structural form of the hip joints is difficult to accurately display by X-rays, and the hip joints are damaged by radioactivity. The ultrasonic imaging examination can well display the anatomical structures of the hip joint and surrounding soft tissues and the relative positions of the femoral head and the acetabulum, visually observe the cartilage and the bony structure of the hip joint, evaluate the development condition of the acetabulum and the position of the femoral head, and particularly better display the relative positions of the femoral head and the acetabulum for infants less than 4 months without the occurrence of a femoral head ossification center; (2) the ultrasonic imaging diagnosis has important diagnostic value for hidden or critical pathological changes of hip joint dysplasia, especially for infants who are indicated to be abnormal in hip joints or have high risk factors in physical examination; (3) the ultrasonic examination is non-invasive, safe, easy to implement, low in cost and capable of being dynamically observed, and is particularly suitable for screening of high risk groups of the disease and continuous follow-up diagnosis after treatment.

The Graf method is the most commonly used ultrasound DDH assessment method, and is a static method of DDH ultrasound examination pioneered by Graf, Austrian. The method has the advantages of standardization, repeatability, objectivity of reference indexes and the like, and is widely applied to German countries all over the world, particularly Europe. The Graf method requires taking a standard coronal section of the hip joint for measurement. The long axis of the probe is required to be parallel to the axis of the body (tilting of the probe may lead to over-diagnosis) and a standard image of the hip coronal section is obtained at the greater trochanter of the femur. Whether the coronal section is correct is determined by the anatomy of the acoustic image: hyperechoic below the hip joint is the union of cartilage and bone (femoral epiphysis); the middle of the hip joint is the femoral head which is represented as an oval low-echo area with scattered points inside and medium echoes; the lateral side of the femoral head is surrounded by the supraechogenic synovial fold, the joint capsule, the labrum and the low echogenic cartilaginous acetabulum, in that order, and gradually extends over the femoral head as a strongly echogenic bony acetabular rim. All the above anatomical points should be clearly identified, otherwise the ultrasound image cannot be adopted.

In addition to the Graf method, the Femoral Head Coverage (FHC) can be measured by referring to the Morin method, the stability of the hip joint can be reflected by the ratio of the femoral head bony acetabular coverage to the femoral head diameter, and the state of the hip joint can be evaluated.

However, in the existing scheme, the measurement of parameters of hip joints of newborns is complex, and measurement errors are easy to occur. Therefore, how to obtain and improve the measurement accuracy of the hip joint becomes an urgent problem to be solved.

The sectional view of the target hip joint may be a coronal sectional view of the target hip joint, and the sectional view may include the position, morphology and the like of each tissue of the target hip joint. For example, the cut plane view may include the cartilage to bone interface of the target hip joint, the femoral head, the inferior iliac margin, the marginal inflection point (point where the acetabular apex is changed from concave to convex), the flat outer iliac margin, the cartilaginous acetabular apex, the labrum, the joint capsule, the synovial fold, the greater trochanter of the femur, and the like. Wherein, the specific expression form can be that the hyperechoic sound under the target hip joint is the combined part of cartilage and bone (femoral epiphysis plate); the center of the target hip joint is the femoral head which is represented as an oval low-echo area with scattered points inside and medium echoes; the lateral side of the femoral head is surrounded by the supraechogenic synovial fold, the joint capsule, the labrum and the low echogenic cartilaginous acetabulum, in that order, and gradually extends over the femoral head as a strongly echogenic bony acetabular rim.

In an alternative embodiment of the present application, the sectional view of the target hip joint may be read from memory. It will be appreciated that after the sectional view of the target hip joint has been acquired in advance, the sectional view may be saved to memory. When the section diagram is used, the section diagram can be extracted from a memory.

Specifically, the aforementioned transmit/receive sequence controller 102 in the hip imaging system of fig. 1 may be used to excite the ultrasonic probe 100 to transmit ultrasonic waves to the target hip joint, and control the ultrasonic probe 100 to receive the ultrasonic echo returned from the target hip joint, so as to obtain an ultrasonic echo signal, and the processor 103 processes the ultrasonic echo signal/data to obtain a sectional view of the target hip joint. Generally, when transmitting ultrasonic waves to a target hip joint through a probe, the long axis of the probe needs to be parallel to the axis of the body (the inclination of the probe may cause over-diagnosis), and a standard image of the hip joint coronal section is obtained at the greater trochanter of the femur. In addition, the volume data of the target hip joint can be obtained by sending ultrasonic waves to the target hip joint, and the tangent plane diagram of the target hip joint is extracted from the volume data, so that the inaccuracy of the coronal tangent plane caused by manual measurement can be avoided.

Specifically, after the volume data is acquired, the volume data may be sliced to obtain a plurality of sectional views, and then a sectional view with a standard degree higher than a threshold value is acquired from the plurality of sectional views as the sectional view. The cutting can be directly carried out from a preset angle to obtain at least one coronal section map of the target hip joint, namely a section map; or, the volume data is cut in parallel along a preset direction to obtain a plurality of sectional graphs, and then the sectional graph with the standard degree higher than the threshold value is determined from the plurality of sectional graphs; the target shaft can be used as the axis for rotary cutting to obtain a plurality of sectional graphs, and then the sectional graph with the standard degree higher than the threshold value can be determined from the plurality of sectional graphs. In addition, if there are a plurality of sectional views with the standard degree higher than the threshold, the sectional view with the highest standard degree may be selected as the sectional view of the hip joint targeted in the present application, or one of the sectional views with the standard degree higher than the threshold may be arbitrarily selected as the sectional view of the hip joint targeted in the present application. The standard degree can be measured by a standard degree score value of each tangent plane graph obtained through deep learning calculation, or by directly determining the probability that each tangent plane is the standard tangent plane graph through deep learning, and the standard degree can be specifically adjusted according to actual application. Deep learning may also include deep learning approaches that may be convolutional neural networks, recurrent neural networks, and so forth. The manner of obtaining at least one sectional view may be adjusted according to an actual application scenario, and the embodiment of the present application is merely an example and is not limited.

In an alternative embodiment of the present application, after the sectional view of the target hip joint is acquired, the sectional view may be displayed on a display.

302. And acquiring the tissue characteristic information of the target hip joint in the sectional view.

After the sectional view of the target hip joint is obtained, the tissue characteristic information of the target hip joint can be obtained from the sectional view of the target hip joint. The tissue feature information may include morphology, location, size, etc. information of various tissue features of the target hip joint included in the standard image.

For example, if the health status of the target hip joint is determined by the Graf method, the tissue characteristic information to be acquired may include: the flat ilium of the target hip joint, the inferior iliac margin, the labrum, the turning of the bone margin, and the like. When the health state of the target hip joint is determined by the Morin method, it is necessary to include the straight ilium and the femoral head of the target hip joint.

In an alternative embodiment of the present application, the tissue feature information in the sectional view of the target hip joint can be identified by means of deep learning. Specifically, a large number of sectional views may be used for model training, tissue characteristic information in the large number of sectional views is recorded and analyzed, parameters of each tissue characteristic of the sectional views are determined, and a deep learning model at the training position is obtained. Then, after a target hip joint sectional view is obtained, the sectional view is substituted into the model, and the tissue characteristic information included in the sectional view can be determined. The deep learning in the embodiment of the present application may be a convolutional neural network, a recurrent neural network, a cyclic neural network, or the like. In practical applications, which deep learning manner is specifically used may be adjusted according to practical application scenarios, and this is merely an example and is not limited.

303. And determining the measurement information of the target hip joint according to the tissue characteristic information of the target hip joint.

After obtaining the tissue characteristic information of the target hip joint, the measurement information of the target hip joint can be determined according to the tissue characteristic information. The tissue characteristic information may include relative positions, morphologies, sizes, etc. of various tissue characteristics of the target hip joint. The measurement information may include angular measurement information or distance measurement information of various tissue features, or the like. Further, the distance measurement information may also be represented by a scale, for example, the distance measurement information may be a ratio of distances between tissue features of the target hip joint.

In an alternative embodiment of the present application, the measurement information may include bone apex angle and cartilage apex angle. In the following application examples, the bone apex angle may also be referred to as the α angle, and the cartilage apex angle may also be referred to as the β angle. The specific way of determining the bone apex angle and the cartilage apex angle may be: after obtaining tissue characteristic information of the target hip joint, the tissue characteristic information may include tissue characteristics of the straight ilium, the inferior iliac margin, the labrum, the bone edge transition, and the like of the target hip joint, and a baseline, a bone apical line, and a cartilage apical line may be determined from the tissue characteristic information. The angle between the baseline and the bone apical line, i.e. the bone apical angle, and the angle between the baseline and the cartilage apical line, i.e. the cartilage apical angle, are then determined. The base line may be a line corresponding to a straight ilium, the vertex line may be a tangent line between the inferior iliac margin and the lateral rim of the bony acetabulum, and the vertex line may be a connecting line between the labrum and the lateral rim of the bony acetabulum. Illustratively, as shown in fig. 4, baseline 401 is a line corresponding to a straight ilium, crest line 402 is a tangent to the inferior iliac margin and the lateral margin of the bony acetabulum, and cartilage crest line 403 is a line connecting the labrum and the lateral margin of the bony acetabulum. The angle α is the angle between the base line 401 and the vertex line 402, and the angle β is the angle between the base line 401 and the vertex line 403. Specifically, for example, as shown in fig. 5, in a practical application scenario, the α angle and the β angle may be determined according to the baseline, the bone vertex line, and the cartilage vertex line. It should be understood that the positions of the baseline, the vertex line and the vertex line are only exemplarily shown in fig. 4 and fig. 5, and in practical applications, the positions of the baseline, the vertex line and the vertex line may be more precise, which is merely an exemplary illustration and is not limited herein.

In an optional embodiment of the present application, after the bone vertex angle and the cartilage vertex angle are obtained, the state of the target hip joint may be continuously analyzed according to the bone vertex angle and the cartilage vertex angle, so as to obtain reference typing data of the target hip joint, that is, a Graf typing result. For example, after the angle α and the angle β are determined, the state of the hip joint of interest may be determined in combination with age and the like. Specifically, when α angle > is 60 ° and β angle < ═ 55 °, it can be determined that the typing data of the target hip joint is type Ia; when α angle > 60 ° and β angle >55 °, it may be determined that the typing data of the target hip joint is type Ib; when the angle alpha is any value of 50-59 degrees and the age is 0-12 weeks, the typing data of the hip joint of the target can be determined as type IIa; when the alpha angle is any value of 50-59 degrees and the age is more than 12 weeks, determining that the typing data of the target hip joint is type IIb; when the alpha angle is any value of 43-49 degrees and the beta angle is 77 degrees, determining that the typing data of the target hip joint is IIc type; when the angle alpha is any value of 43-49 degrees and the angle beta is more than 77 degrees, the typing data of the target hip joint can be determined to be D type.

In an alternative embodiment of the present application, the measurement information may comprise an FHC. The FHC is the ratio of the distance between the medial tangent and the baseline of the femoral head to the distance between the medial tangent and the lateral tangent of the femoral head. The distance between the medial tangent and the lateral tangent of the femoral head can also be understood as the diameter of the femoral head. The way to determine the distance of the femoral head medial tangent to the baseline and the diameter of the femoral head may be: determining the medial tangent of the femoral head, the lateral tangent of the femoral head, and the baseline, then calculating the distance between the medial tangent of the femoral head and the lateral tangent of the femoral head, which can also be denoted as D, and calculating the distance between the medial tangent of the femoral head and the baseline, which can also be denoted as D. The value of FHC is then determined based on the ratio of D to D, i.e., D/D. Illustratively, as shown in FIG. 6, after the straight ilium of the target hip joint is determined, a baseline 601 is determined. After the femoral head is identified, a lateral tangent 602 to the femoral head is identified as well as a lateral tangent 603 to the femoral head. The distance D between the medial tangent 603 and the baseline 601 is calculated, and the distance D between the medial tangent 603 and the lateral tangent 602 is calculated. Then determining the ratio D/D of D to D to obtain the value of FHC. Specifically, for example, in practical applications, as shown in fig. 7, after determining the baseline, the medial femoral head tangent and the lateral femoral head tangent, the distance D between the baseline and the medial femoral head tangent, and the medial femoral head tangent and the lateral femoral head tangent D can be calculated. In the embodiment of the application, the value of the FHC of the target hip joint can be determined according to the tissue characteristics of the target hip joint, and compared with manual measurement, the measurement error can be reduced. It should be understood that the positions of the baseline, the medial femoral head tangent line and the lateral femoral head tangent line are only exemplarily shown in fig. 6 and 7, and in practical applications, the positions of the baseline, the medial femoral head tangent line and the lateral femoral head tangent line may be more precise.

In an alternative embodiment of the present application, after the value of FHC is determined, the target hip may be further analyzed to determine the status of the target hip. For example, when the value of FHC > 58%, the target hip is in a developmentally normal state; when the value of FHC is < 33%, the target hip is in an dysplastic state; when the value of FHC is any value between 33% and 58%, the target hip joint is in a partially normal and partially abnormal state.

In an optional embodiment of the present application, the measurement information may include both the α angle and the β angle, and the FHC, so as to perform a comprehensive analysis on the state of the target hip joint in combination with the α angle, the β angle, and the FHC, so that the obtained state of the target hip joint is more accurate.

304. And displaying the section diagram and the measurement information.

After the standard section and the corresponding measurement information are obtained, the section diagram and the measurement information can be displayed in a display. Wherein the measurement information may include angle measurement information or distance measurement information of various tissue features of the target hip joint, and the like. Further, the distance measurement information may also be represented by a scale, for example, the distance measurement information may be a ratio of distances between tissue features of the target hip joint.

In an alternative embodiment of the present application, the measurement information may include an angle α and an angle β. After the α and β angles are obtained, the tangent plane and the α and β angles can be displayed simultaneously. Specifically, the α angle and the β angle may be displayed in a manner of superimposing on the sectional view, or may be displayed on the periphery of the sectional view. Illustratively, as shown in fig. 8, the α angle and the β angle may be displayed superimposed on the sectional view. As shown in fig. 9, the α angle and the β angle may be displayed at the periphery of the sectional view.

In an alternative embodiment of the present application, after the value of FHC is obtained, the section diagram and the value of FHC may be displayed simultaneously. The FHC value may be displayed on the section map, or may be displayed on the periphery of the section map. Exemplarily, as shown in fig. 10, the value of FHC may be displayed superimposed on the sectional view, wherein the distance D between the medial tangent of the femoral head and the lateral tangent of the femoral head, and the distance D between the medial tangent of the femoral head and the baseline may also be displayed simultaneously. As shown in FIG. 11, the FHC value can also be displayed on the periphery of the sectional view.

In an alternative embodiment of the present application, the measurement information may also include both the α and β angles and the values of FHC, so that the tangent plane map and the values of α, β and FHC may also be displayed simultaneously.

In the application, a sectional view of a target hip joint is obtained, then the tissue characteristic information of the target hip joint in the sectional view is detected, and the measurement information of the hip joint is determined according to the tissue characteristic information. Therefore, in the present application, the characteristics of the hip joint in the sectional view can be automatically detected by identifying the sectional view, and the measurement information of the hip joint can be determined by organizing the characteristic information. The measurement is not needed manually, the measurement efficiency is improved, and the measurement accuracy of the hip joint is improved.

Further, when the target hip joint includes a condition in which the respective tissue features are not co-planar, the target tissue feature may not need to be measured. Specifically, referring to fig. 12, another schematic flow chart of the imaging method of the hip joint in the embodiment of the present application may include:

1201. and acquiring a sectional view of the target hip joint.

Step 1201 in the embodiment of the present application is similar to step 301 in fig. 3, and details are not repeated here.

1202. And judging whether the section graph meets the preset standard, if so, executing a step 1204, and if not, executing a step 1203.

After the sectional view is obtained, it may be further determined whether the sectional view meets a preset standard, and if the sectional view meets the preset standard, step 1204 may be executed to continue the tissue characteristic information and the measurement information of the sectional view. If the section view does not meet the preset standard, step 1203 may be executed to directly obtain a first confidence of the determination result that the section view does not meet the preset standard.

Specifically, the step of judging whether the section diagram meets the preset standard may be: and identifying whether the form of the preset tissue characteristic in the section map is a preset form, if the preset tissue characteristic is the preset form, the section map conforms to a preset standard, and if the tissue characteristic is not the preset form, the section map does not conform to the preset standard. For example, the acetabulum morphology of the target hip joint may be identified, and if the acetabulum morphology of the target hip joint is a preset morphology, step 1204 is performed, that is, reference typing data of the target hip joint is determined according to the acetabulum morphology; if the acetabulum form of the target hip joint is not the preset form, step 1203 is executed to obtain the tissue characteristic information of the target hip joint in the sectional view. In general, in practical applications, if the state of the target hip joint is dislocated, the health state of the target hip joint can be determined, and the measurement information of the target hip joint does not need to be acquired any more.

For example, the acetabulum morphology of the target hip joint may be identified, after a tangent plane diagram of the target hip joint is obtained, the acetabulum position of the target hip joint may be determined through deep learning or by comparing pixel value differences, and then the acetabulum morphology of the target hip joint is obtained according to the acetabulum position. And then whether the obtained acetabulum form of the target hip joint is a preset form or not can be judged. If the acetabulum form of the target hip joint is a preset form, the tissue characteristic information of the target hip joint included in the sectional view can be continuously acquired; if the acetabulum form of the target hip joint is not a preset form, the reference typing data of the target hip joint can be determined directly according to the acetabulum form of the target hip joint. The predetermined configuration may be such that the cartilage of the target hip joint may cover the femoral head. In particular, the acetabular morphology of the target hip joint may be identified by means of deep learning. The deep learning mode can be a convolution neural network, a feature detection network, a recurrent neural network, a cyclic neural network and the like. Specifically, a large number of sectional views in preset shapes are used for model training to obtain characteristic parameters of the acetabulum shapes in the preset shapes, and then after the sectional views are obtained, each sectional view is substituted into the model to identify the acetabulum shape of the target hip joint. The acetabulum morphology of the target hip joint can also be determined by means of pixel value comparison. For example, the pixel value of each pixel point in the sectional view can be determined by a conventional pixel value comparison method, the acetabulum contour of the target hip joint in the sectional view is determined according to the difference between the pixel values, and then the acetabulum morphology of the target hip joint is determined according to the acetabulum contour.

In an optional embodiment of the present application, after the section map is displayed, input data of the section map may also be received, and whether the section map meets a preset standard is determined according to the input data, if yes, step 1204 is performed, and if not, step 1203 is performed. For example, after displaying the section view, the user may manually identify whether the section view is in the preset form according to the section view. If the acetabulum form of the target hip joint is the preset form, the step 604 may be continuously executed, and if the acetabulum form of the target hip joint is not the preset form, the step 603 may be continuously executed.

In addition, in an alternative embodiment of the present application, in addition to determining the acetabular morphology of the target hip joint, it may also be determined whether the sectional view is a standard sectional view to determine whether the sectional view meets a preset standard. Whether the section map meets the preset standard or not can be judged through other tissue characteristics. For example, the tissue features may include the ilium, labrum, bone edge transition, ilium inferior margin, femoral head, etc. of the target hip joint, and the identification of the tissue features may be similar to the identification of the morphology of the acetabulum and will not be described herein. It can be determined whether the morphology of the tissue feature satisfies the following characteristics: the center of the target hip joint is the femoral head which is represented as an oval low-echo area with scattered points inside and medium echoes; the lateral side of the femoral head is surrounded by the supraechogenic synovial folds, the joint capsule, the labrum and the low echogenic cartilaginous acetabulum, in that order, and gradually extends over the femoral head to a hyperechogenic bony acetabular rim, and so on. If the tissue features in the sectional view do not satisfy the above conditions, it may be determined that the sectional view does not satisfy the preset criteria, step 1203 may be continuously performed, a first confidence degree of the determination result that the sectional view does not satisfy the preset criteria is determined, and the first confidence degree is displayed. If the tissue characteristics in the sectional view meet the above conditions, it may be determined that the sectional view meets the preset criteria, and step 1204 may be continuously performed to obtain the tissue characteristic information of the target hip joint in the sectional view.

Therefore, in the embodiment of the present application, it may be determined whether the sectional view meets the preset standard, and usually, if the target hip joint is dislocated or the tissue features in the sectional view are not coplanar due to irregular scanning, the obtained sectional view does not meet the preset standard. The measurement information does not need to be acquired from the section diagram which does not accord with the preset standard, the inaccuracy of the acquired measurement information can be avoided, and the accuracy is improved.

1203. A first confidence level is determined and the confidence level is displayed.

After the section map is determined not to meet the preset standard, the confidence coefficient of the judgment result, namely the first confidence coefficient, can be calculated, and the first confidence coefficient is displayed.

The first confidence may be understood as the confidence of the judgment result that the section diagram does not meet the preset standard. For example, if the sectional view is not a standard sectional view, the first confidence may be a probability that the sectional view is not a standard sectional view, or if a plurality of tissue features in the sectional view are not coplanar, it may be determined that the target hip joint is in a dislocation state, a suspected dislocation state, or the like, and the first confidence may be a probability that the target hip joint is in a dislocation state, a suspected dislocation state, or the like.

For example, if the sectional view of the target hip joint is determined to be a non-standard sectional view. Then, the specific way of determining the first confidence may be to determine each tissue feature in the sectional view, calculate the probability that each tissue feature is the standard tissue, and determine the first confidence that the sectional view is the nonstandard sectional view by combining the relative position, form and other features of each tissue feature according to the relative form of each tissue feature.

For example, if it is determined that the plurality of tissue features of the target hip joint are not coplanar, the target hip joint is in a dislocated state, for example. Then the probability that each tissue feature in the sectional view of the target hip joint is the standard tissue can be determined, the relative position, morphology and the like of each tissue feature can be determined, and then the first confidence coefficient that the plurality of tissue features of the target hip joint are not coplanar can be determined according to the probability that each tissue feature is the standard tissue and the relative position of each tissue feature.

Optionally, the calculating the confidence level may be directly obtaining the first confidence level when the sectional view of the target hip joint is determined not to meet the preset standard before determining whether the sectional view meets the preset standard.

It is understood that if the sectional view does not meet the preset standard, one scenario may be that the sectional view is a non-standard sectional view, and another scenario may be that the tissue features in the sectional view are not coplanar, for example, the target hip joint is a subluxation, or has already dislocated.

Specifically, after the sectional view is obtained, the probability that each tissue feature in the sectional view meets the standard tissue feature can be determined in a deep learning manner, and then the first confidence coefficient is calculated by combining the relative position, the form and the like of each tissue feature. Exemplary criteria to which various organizational features may conform may include: the hyperechoic underlying target hip joint is the union of cartilage and bone (femoral epiphysis); the center of the target hip joint is the femoral head which is represented as an oval low-echo area with scattered points inside and medium echoes; the lateral side of the femoral head is surrounded by the supraechogenic synovial fold, the joint capsule, the labrum and the low echogenic cartilaginous acetabulum, in that order, and gradually extends over the femoral head as a strongly echogenic bony acetabular rim. Therefore, the tissue features included in the sectional view can be detected in a deep learning manner, whether the tissue features included in the sectional view are the standard or not can be judged according to the tissue features included in the sectional view, the probability that each tissue feature meets the preset standard is obtained, and the first confidence coefficient is calculated by combining the relative position, the form and the like of each tissue feature.

In an optional embodiment of the present application, after obtaining the first confidence level, the tangent plane and the first confidence level may be displayed at the same time. Specifically, the first confidence may be displayed by superimposing on the sectional view, or the first confidence may be displayed on the periphery of the sectional view, which may be specifically adjusted according to the actual application scenario, and is not limited herein. For example, as shown in fig. 13, the first confidence Q may be displayed superimposed on the tangent plane diagram. In the embodiment of the application, the section view and the confidence coefficient can be displayed simultaneously, so that an operator can observe the target hip joint more accurately according to the confidence coefficient and determine the state of the target hip joint more accurately.

In an optional embodiment of the present application, after determining that the section map does not meet the preset standard, a prompt message, such as a prompt message of "dislocated", "half dislocated", or "image not standard", may be generated for the section map. And after the prompt message is generated, the section drawing and the prompt message are displayed at the same time. Specifically, the prompt information may be displayed on the sectional view in an overlapping manner, or the prompt information may be displayed on the periphery of the sectional view, which may be specifically adjusted according to the actual application scenario, and is not limited herein. Routinely, as shown in FIG. 14, a prompt message "dislocated!may be displayed superimposed on the dislocated sectional view! | A | A ".

In an alternative embodiment of the present application, after determining that the section map does not meet the preset standard, a corresponding graph, a simulated three-dimensional image, and the like may be generated according to the section map. For example, if the plurality of tissue features in the sectional view are not coplanar and the target hip joint is in a dislocation state, a simulated three-dimensional image can be generated according to the sectional view, and the dislocation state of the target hip joint is displayed in three dimensions. Or a dislocation graph is generated from the section graph to display the dislocation state of the hip joint.

In an optional embodiment of the present application, the first pseudo color image may be generated according to the first confidence, and specifically, the first pseudo color image may be generated according to a preset rule. For example, a first confidence level above a threshold may correspond to a more prominent color, e.g., green, red, etc. The first confidence is below a threshold, which may correspond to a light color, e.g., gray, etc. Alternatively, the pseudo-color images with different gray levels can be generated according to the value of the first confidence level, wherein the higher the first confidence level is, the higher the gray level value is, the lower the first confidence level is, the smaller the gray level value is, and the like.

1204. And acquiring the tissue characteristic information of the target hip joint in the sectional view.

After the section map is determined not to meet the preset standard, the tissue characteristic information of the target hip joint in the section map can be obtained. The tissue feature information may include morphology, location, size, etc. information of various tissue features of the target hip joint included in the standard image.

In an alternative embodiment of the present application, when acquiring the morphology of the acetabulum of the target hip joint from the sectional view, the tissue characteristic information of the target hip joint may be acquired, and the tissue characteristic information may include the morphology, position, size, and the like of each tissue characteristic in the target hip joint. Besides the acetabulum morphology of the target hip joint can be obtained from the tissue characteristic information, the tissue position information of the target hip joint can be obtained, and the measurement information of the target hip joint can be determined through the tissue position information. The method may be specifically adjusted according to an actual application scenario, and is not limited herein.

1205. And determining the measurement information of the target hip joint according to the tissue characteristic information of the target hip joint.

1206. And displaying the section diagram and the measurement information.

Specifically, steps 1204, 1205, and 1206 in this embodiment are similar to steps 302, 303, and 304 in fig. 3, and are not described herein again.

In an alternative embodiment of the present application, after determining the measurement information of the target hip joint, a second confidence level of the measurement information may also be obtained. The process of specifically determining the second confidence may be to calculate the second confidence by combining the probability that each tissue feature in the sectional view is the standard tissue and geometric features such as relative positions and forms of each tissue feature. The more specific calculation of the second confidence degree is similar to the calculation method of the first confidence degree in step 1203, and details thereof are not repeated here. After the second confidence is obtained, the section view, the measurement information, the second confidence and the like can be displayed on the display. For example, as shown in fig. 15, the α angle, the β angle, and the confidence may be displayed in a superimposed manner in the tangent plane. For another example, as shown in fig. 16, the FHC and the second confidence may be displayed simultaneously in a superimposed manner in the sectional view. Therefore, in the embodiment of the application, after the measurement information is obtained, the second confidence level may be further obtained, so that the operator may simultaneously perform combined observation on the measurement information and the second confidence level to determine the accuracy of the measurement information.

In an optional embodiment of the present application, the second pseudo color image may be generated according to the second confidence, and specifically, the second pseudo color image may be generated according to a preset rule. For example, the second confidence level is above a threshold and may correspond to a more prominent color, e.g., green, red, etc. The second confidence is below a threshold, which may correspond to a light color, e.g., gray, etc. Alternatively, the pseudo-color image with different gray levels can be generated according to the value of the second confidence level, wherein the higher the second confidence level is, the higher the gray level value is, the lower the second confidence level is, the smaller the gray level value is, and the like. Therefore, in the embodiment of the application, the result of the second confidence coefficient can be visually displayed in a color chart manner, so that the observation of an operator is facilitated.

In the application, a sectional view of a target hip joint is obtained first, and whether the sectional view meets a preset standard or not can be judged first, and generally, if the target hip joint is dislocated or various tissue features in the sectional view are not coplanar due to irregular scanning, the obtained sectional view does not meet the preset standard. The measurement information does not need to be acquired from the section diagram which does not accord with the preset standard, the inaccuracy of the acquired measurement information can be avoided, and the accuracy is improved. If the section diagram meets the preset standard, the tissue characteristic information of the target hip joint in the section diagram can be obtained, and the measurement information of the hip joint is determined according to the tissue characteristic information. Therefore, in the present application, the characteristics of the hip joint in the sectional view can be automatically detected by identifying the sectional view, and the measurement information of the hip joint can be determined by organizing the characteristic information. The measurement is not needed manually, the measurement efficiency is improved, and the measurement accuracy of the hip joint is improved.
