Problems solved by technology

Although this method establishes a three-dimensional data model to analyze the position of the acetabulum, evaluate the state of the acetabulum, clarify the bone volume around the acetabulum, and calculate the bone thickness around the acetabulum, but this method cannot accurately calculate the ability of the acetabulum to align with the femur after surgery. The coverage rate of the bone cannot be evaluated for the stability of the connection shape between the acetabulum and the femoral head after surgery.

Embodiment 1

[0025] The present application relates to a system for judging the shape of the acetabulum. The system can establish a three-dimensional image of the hip joint according to pre-collected spiral CT scan or MRI data, and perform isovalue cutting and parallel light on the established three-dimensional image of the hip joint. The method of projection processing is used to obtain contour graphs that characterize the spatial shape of the acetabulum by using the arrangement of contour lines, and analyze by superimposing the contour images of the acetabulum and the contour images of the femoral head. The coincidence degree and sparse change trend of the superimposed contour lines can assist the medical staff to accurately judge the relative position of the acetabulum and the femoral head and the degree of acetabular dysplasia. The system at least includes a processing unit 1 , an analysis unit 2 , a comparison unit 3 and a control unit 4 .

[0026] According to a specific embodiment, ...

Embodiment 2

[0036] This embodiment is a further improvement of Embodiment 1, and repeated content will not be repeated.

[0037] For patients with hip dysplasia, the acetabulum cannot effectively cover the end of the femoral head, and the acetabulum and the femoral head cannot form a "dome-like" space contour that matches each other. In the above case, although the end of the femoral head is partially located in the concave space of the acetabulum, the acetabulum is in an inclined state with respect to the axial direction of the femoral head, that is, the position of the dome of the acetabulum cannot match the position of the femoral head. The dome apex positions of the bones correspond to each other, and the dome apex position of the acetabulum is severely offset inward from the edge, resulting in an ineffective matching of the “dome-like” spatial contours of the acetabulum and the femoral head. When the patient is standing, the pressure of the body weight on the hip joint is decomposed ...

Embodiment 3

[0041] The present application relates to a method for judging the shape of the acetabulum. In addition, the present invention may also relate to a method for measuring the stability of the hip joint. It includes at least the following steps:

[0042] Generate a three-dimensional image of the hip joint from pre-acquired spiral CT scan or MRI data of the hip joint;

[0043] The three-dimensional image of the acetabulum and the three-dimensional image of the femoral head are respectively cut out from the generated three-dimensional image of the hip joint;

[0044] On the 3D image of the acetabulum and the 3D image of the femoral head, use the space grid to intercept the slice along the direction of the gravity line of the longitudinal axis of the body;

[0045] Obtain the contour graph of the acetabulum and the contour graph of the femoral head by projecting several slices cut out from the three-dimensional image of the acetabulum and the three-dimensional image of the femoral ...

Abstract

The invention relates to a system for judging the shape of an acetabulum, which at least comprises a processing unit (1) capable of generating a three-dimensional image according to spiral CT (Computed Tomography) scanning or MRI (Magnetic Resonance Imaging) data, and the processing unit (1) is capable of generating a three-dimensional image of a hip joint according to pre-acquired spiral CT scanning or MRI data of the hip joint and transmitting a processing result to an analysis unit (2); the analysis unit (2) intercepts three-dimensional images of the acetabulum and the femoral head from the received three-dimensional images of the hip joint respectively, and isoline images of the acetabulum and the femoral head are generated by performing same-value cutting on the three-dimensional images of the acetabulum and the femoral head respectively; the comparison unit (3) judges the spatial form of the hip joint by comparing whether the trends and forms of the isolines of the corresponding surface areas of the acetabulum and the femoral head are matched or not. The invention further relates to a method for judging the shape of the acetabulum.

Description

technical field [0001] The invention relates to the technical field of acetabular shape analysis, in particular to a system and method for judging the shape of the acetabulum. Background technique [0002] In the diagnosis and surgical evaluation of hip joint diseases, medical staff usually need to understand the normal spatial morphology of the acetabulum and femoral head, the coverage of the acetabulum to the end of the femoral head, and the adaptation between the acetabulum and the femoral head before surgery. degree. Although the currently widely used X-ray films can provide certain useful information, because the three-dimensional structure of the hip joint is compressed and integrated into the two-dimensional plane, information loss inevitably occurs, so it cannot reflect the normal space of the hip joint in detail and accurately. form. [0003] At present, although relevant research institutions can use 3D reconstruction methods to convert 2D plane data into 3D stru...
