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

Ultrasonic imaging is widely used for analyzing various diseases, and can be used for carrying out ultrasonic imaging on a target hip joint so as to analyze the characteristics of the target hip joint to determine the health state of the target 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 map is correct is determined by the anatomy of the ultrasound 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.

Therefore, when performing DDH ultrasound examination according to the Graf method, the requirement for slice images is high, and if the slices are not standard, the measurement will be biased. Therefore, how to obtain a more accurate measurement result is an urgent problem to be solved.

In one embodiment of the present application, the volume data of the target hip joint may be obtained by the probe sending ultrasonic waves to the target hip joint and receiving ultrasonic echoes returned from the target hip joint in the hip joint imaging system in fig. 1. In particular, since the probe in the hip joint imaging system can be a three-dimensional probe comprising three-dimensionally arranged array elements, the ultrasonic echo signal returned from the target hip joint can be directly acquired by the three-dimensional probe to obtain the volume data of the target hip joint. Or, the hip joint imaging system may further include a mechanical scanning device, the mechanical scanning device drives the probe to move, and the ultrasonic echo signals returned from the target hip joint are received from different angles, so as to obtain volume data of the target hip joint.

The volume data may be stored in a memory after the volume data is obtained by transmitting ultrasonic waves to the target hip joint through an ultrasonic probe in a hip joint imaging system or other ultrasonic imaging equipment within a preset time period and receiving ultrasonic echoes returned from the target hip joint. Therefore, the volume data of the target hip joint in the embodiment of the present application can be read from the memory.

302. At least one slice is determined from the volume data.

After obtaining the volume data of the target hip joint, at least one section of the target hip joint is extracted from the volume data, wherein the at least one section can be one or a plurality of sections, and the plurality of sections in the application refers to two or more than two. The slice view may also be referred to as coronal slice view hereinafter.

In an embodiment of the present application, the at least one section may be a section with a standard degree greater than a threshold, and the standard degree may be measured by various parameters, for example, a probability that each section is a section, or a standard degree score value determined in a preset manner for each section, and the like. In addition, the at least one sectional view may also be a preset contour of the tissue, or may also be a sectional view determined in other manners, and the like, which is not limited in this application.

In particular, the cut-out may be a coronal cut-out of the target hip joint, which may include various tissue features of the target hip joint, for example, which may include, but is not limited to, the following tissue features: cartilage to bone interface, femoral head, ilium inferior margin, bone edge turning point (point where acetabular apex is changed from concave to convex), flat ilium outer margin, cartilaginous acetabular apex, labrum, joint capsule, synovial fold, femoral greater trochanter. In general, in an actual ultrasound image, the features of the sectional view of the target hip joint 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.

In one embodiment of the present application, determining at least one cut plane from the volume data may comprise: the cutting can be directly carried out from a preset angle to obtain at least one coronal section view of the target hip joint, namely at least one section view of the target hip joint in the embodiment of the application; or, the volume data is cut in parallel along the preset direction to obtain a plurality of sectional views, and then at least one sectional view with higher standard degree is determined from the plurality of sectional views to be used as at least one sectional view of the target hip joint in the embodiment of the application; the hip joint may be obtained by performing a rotary cutting with the target axis as the axis to obtain a plurality of sectional views, and then determining at least one sectional view with a higher standard degree from the plurality of sectional views as at least one sectional view of the target hip joint in the embodiment of 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 of each tangent plane being the 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 at least one sectional view is extracted from the volumetric image of the target hip joint, the at least one sectional view may also be displayed on the display. When there is only one sectional view, the one sectional view may be directly displayed in the display. When there are multiple section diagrams, the arrangement and adjustment of the multiple section diagrams can be carried out according to a preset mode, and the multiple section diagrams are displayed. For example, the higher-level slice may be larger in size or located closer to the center, the lower-level slice may be smaller in size or located closer to the edge, and so on. Therefore, in the embodiment of the present application, after obtaining at least one sectional view, the at least one sectional view may be displayed, so that the operator may more intuitively observe the target hip joint.

Illustratively, the at least one cut-out may include one or more cut-outs, which may be as shown in fig. 4.

303. And determining target tissue characteristic information of the target hip joint according to the at least one section graph.

After obtaining the at least one sectional view, determining target tissue characteristic information of the target hip joint according to the at least one sectional view. The target tissue characteristic information may include morphology, location, size, etc. characteristics of individual tissues in the target hip joint.

For example, each of the at least one sectional view may include the morphology, location, etc. of the tissue of the straight ilium, the inferior iliac margin, the labrum, the edge transition, etc. of the target hip joint, and then the target tissue characteristic information of the target hip joint may be determined based on the tissue characteristics included in each sectional view.

Specifically, the tissue features in each standard image can be identified in a deep learning manner, and tissue feature information in each standard image is obtained. Before this, a large number of sectional views may be used for model training to obtain parameters of each tissue feature of the sectional views, and then after the at least one sectional view is obtained, each sectional view is substituted into the model, so that the tissue feature information included in each sectional view can be determined. In addition, the tissue characteristic information in each standard image can also be identified through a traditional identification mode, for example, the value of each pixel point in each sectional view is obtained, and then each tissue characteristic of the target hip joint in each sectional view is determined through the difference value between the pixel values, so that the characteristic information of each sectional view is obtained. More specifically, the manner of identifying the tissue features in each standard image may be adjusted according to the actual application scenario, and the embodiment of the present application is only an exemplary illustration and is not limited.

In an alternative embodiment of the present application, the at least one sectional view may be a sectional view, and the tissue characteristics of the target hip joint included in the sectional view may be identified to obtain the target tissue characteristic information of the target hip joint. Exemplarily, a first cut-plane view is taken as an example. If the at least one sectional view includes a first sectional view, the tissue characteristics of the target tissue in the first sectional view can be identified to obtain first tissue characteristic information, and the first tissue characteristic information is used as target tissue characteristic information.

In an alternative embodiment of the present application, when the at least one sectional view includes only one sectional view, the sectional view with the highest degree of standardization may be determined as the one sectional view from among the sectional views of the volume image of the hip joint of interest when the one sectional view is acquired.

In an alternative embodiment of the present application, when the at least one cut-out includes a plurality of cut-outs, the plurality of fingers is two or more. The tissue characteristics of the target hip joint corresponding to each sectional drawing one by one can be determined, and the tissue characteristic information corresponding to each sectional drawing one by one is obtained according to the tissue characteristics of the target hip joint corresponding to each sectional drawing one by one and is used as the target tissue characteristic information of the target hip joint. In addition, if the at least one sectional view includes a plurality of sectional views, the tissue characteristic information corresponding to part of the sectional views in the plurality of sectional views may be obtained as the target tissue characteristic information of the target hip joint. For example, only the tissue feature information corresponding to 3 sectional views one by one may be acquired as the target tissue feature information of the target hip joint. That is, all or part of the tissue feature information corresponding to the sectional views one to one may be obtained, and the number of the specific sectional views may be adjusted according to the actual application scenario, which is not limited in the present application.

For example, taking two of the sectional views as an example, if the plurality of sectional views include a second sectional view and a third sectional view, the second sectional view may be identified to obtain second tissue characteristic information, the third sectional view may be identified to obtain third tissue characteristic information, and the second tissue characteristic information and the third tissue characteristic information are used as target tissue characteristic information of the target hip joint.

In an alternative embodiment of the present application, when the at least one cut-out includes a plurality of cut-outs, the plurality of fingers is two or more. The tissue characteristics of the target hip joint corresponding to each sectional drawing can be determined, and the tissue characteristics of the target hip joint corresponding to each sectional drawing are fused to obtain the target tissue characteristic information of the target hip joint. The specific fusion mode may be that after the tissue features included in each sectional view are obtained, the target tissue feature information included in each sectional view is fused according to preset weight information, so as to obtain the target tissue feature information of the fused target hip joint. The preset weight information may be determined according to the standard degree of each standard section. For example, the confidence of each sectional view may be calculated by deep learning. The confidence may be understood as a standard degree for measuring each sectional view. The deep learning can include a convolutional neural network, a recurrent neural network, a cyclic neural network, and the like. The weight of the tissue features in each slice may then be determined based on the confidence, e.g., the higher the confidence the greater the weight of the tissue features in the standard images. And fusing according to the weight occupied by the tissue characteristics in each sectional view to obtain a fused image, and determining the target tissue characteristic information of the fused target hip joint according to the fused image. More specifically, the pixel value of each pixel point may be determined according to the weight occupied by the tissue feature in each sectional view, so as to obtain the fused image. In addition, when the at least one sectional view includes a plurality of sectional views, the one-to-one corresponding tissue features in a part of the sectional views may also be acquired, and the one-to-one corresponding tissue features in the part of the sectional views may be fused to obtain a fused image. The number of the section maps corresponding to the specific fusion tissue features may be adjusted according to the actual application scenario, and is not limited herein.

Exemplarily, two sectional views are taken as an example for explanation. If the plurality of sectional views include a fourth sectional view and a fifth sectional view, the fourth sectional view can be identified to obtain fourth tissue characteristic information, the fifth sectional view can be identified to obtain fifth tissue characteristic information, and the fourth tissue characteristic information and the fifth tissue characteristic information are fused to obtain a fused image. And identifying the fused image to obtain the target tissue characteristics.

In an alternative embodiment of the present application, the fused image may also be displayed.

In an alternative embodiment of the present application, the tissue characteristic information in each sectional view may also be directly fused to obtain the target tissue characteristic information. After the tissue characteristic information included in each sectional view is obtained, the tissue characteristic information included in each sectional view is fused according to preset weight information, and the fused target tissue characteristic information of the target hip joint is obtained. The preset weight information may be determined according to the standard degree of each standard section. For example, the confidence of each sectional view may be calculated by deep learning. The confidence may be understood as a standard degree for measuring each sectional view. The deep learning can include a convolutional neural network, a recurrent neural network, a cyclic neural network, and the like. The weight of the tissue features in each slice may then be determined based on the confidence, e.g., the higher the confidence the greater the weight of the tissue features in the standard images.

In the embodiment of the application, after a plurality of sectional views are determined, tissue characteristic information in the sectional views is extracted, the tissue characteristic information in the sectional views is fused to obtain a fused image, and relevant parameters of a target hip joint are measured according to the fused image. Therefore, the parameters of the target hip joint can be measured by combining a plurality of standard tangent planes, so that the obtained parameters are more accurate. And the measurement error can be reduced compared with manual measurement.

In an optional embodiment of the present application, after fusing each standard slice to determine the fused target analysis parameter, the fused target analysis parameter and the fused image may be displayed. Specifically, the target analysis parameters, such as the α angle and the β angle, may be displayed superimposed on the sectional view, as exemplarily shown in fig. 5; the target analysis parameters may also be displayed at the perimeter of the cut-plane, illustratively as shown in fig. 6.

Or analyzing each section map to obtain the analysis parameters corresponding to each section map one by one. For example, two sectional views are taken as an example for explanation, when the at least one sectional view includes a second sectional view and a third sectional view, after second tissue characteristic information is obtained according to the second sectional view and third tissue characteristic information is obtained according to the third sectional view, the second tissue characteristic information is analyzed to obtain a second analysis parameter, and the third characteristic information is analyzed to obtain a third analysis parameter. For example, taking two sectional views as an example, one of the second sectional views may be analyzed to obtain α and β angles corresponding to the second sectional view, and one of the third sectional views may be analyzed to obtain α and β angles corresponding to the third sectional view. In the embodiment of the application, after a plurality of sectional views are determined, the tissue characteristic information of each standard image in the plurality of sectional views is extracted, and the analysis parameters are obtained by measuring according to the tissue characteristic information in each sectional view, so that the parameters of the target hip joint can be automatically measured, and the efficiency of obtaining the parameters of the target hip joint is improved. And the target hip joint can be more comprehensively observed by combining a plurality of standard images and corresponding analysis parameters, so that the observation result of the operator on the target hip joint is more accurate. And the measurement error can be reduced compared with manual measurement.

In an alternative embodiment of the present application, each of the plurality of sectional views and the one-to-one corresponding analysis parameter may be displayed simultaneously, for example, a second sectional view and the corresponding α and β angles, and a third sectional view and the corresponding α and β angles may be displayed simultaneously. The section diagram and the analysis parameters may be displayed in a superimposed manner, or the analysis parameters may be displayed around the section diagram, which may be specifically adjusted according to the actual application scenario.

In an alternative embodiment of the present application, the target analysis parameters of the target hip joint may simultaneously include analysis parameters corresponding to the fused image, and analysis parameters corresponding to each standard slice one by one. Therefore, the analysis parameters of the fused image corresponding to the fused image and the analysis parameters of each sectional view corresponding to one can be displayed simultaneously. When displaying each section and the analysis parameters corresponding to each section, the displayed position and size may be adjusted according to the standard degree of each standard section, for example, if the standard degree of the first standard section is higher, the occupied size may be larger. Specifically, for example, as shown in fig. 7, the standard section analysis result, the fusion section analysis result, and the candidate analysis result may be displayed at the same time. The standard section analysis result is one of the section maps with the highest standard degree and the corresponding analysis parameter, and the alternative analysis result may be the section map with the second lowest standard degree and the corresponding analysis parameter. The fused slice analysis results may include fused images and corresponding analysis parameters. Therefore, in the embodiment of the application, analysis parameters for analyzing the tissue characteristic information of each standard section and analysis parameters for analyzing the fusion image can be simultaneously displayed, so that an operator can comprehensively observe a target hip joint according to a plurality of displayed section images, and the state observation of the target hip joint is more accurate. In the embodiment of the application, the fused image and the corresponding analysis parameters as well as each independent standard image and the one-to-one corresponding analysis parameters can be displayed simultaneously, so that an operator can combine various analysis parameters to observe a target hip joint more accurately and more comprehensively to obtain a more accurate and more comprehensive observation result.

Therefore, the standard sectional drawing of the target hip joint is extracted through the three-dimensional volume data of the target hip joint, and the target analysis parameters are determined according to the standard sectional drawing. The obtained target analysis parameters are more accurate relative to the manually obtained sectional view, and the measurement error of the target analysis parameters is reduced.
