Abstract

In the technical solution of a method, device and computer equipment for processing and generating the center of the femoral head of the hip joint provided by the embodiment of the present invention, the outer surface points of the femoral head are generated according to the pre-acquired hip joint data through the isosurface extraction algorithm Set, the outer surface point set includes multiple data points, select the vertex of the femoral head from multiple data points, and generate the initial sphere center coordinates and radius according to the acquired vertex coordinates of the femoral head, according to the initial sphere center coordinates and the radius and the obtained initial point coordinates of the femoral head to generate the updated spherical center coordinates and radius. If the coordinate difference between the updated spherical center coordinates and the initial spherical center coordinates is less than the preset difference value, the updated spherical center coordinates are output. The coordinates and radius of the center can reduce the workload of manual extraction, improve the accuracy of obtaining the center of the femoral head, and the efficiency of obtaining the center of the femoral head.

Description

【Technical field】 [0001] The invention relates to the technical field of medical electronics, in particular to a method, device, storage medium and computer equipment for processing and generating the center of the femoral head of the hip joint. 【Background technique】 [0002] With the development of technology, the automatic planning of hip replacement has become a research hotspot, and in the automatic planning, the determination of the center of rotation of the femur is the key. The upper part of the femoral head is approximately a sphere, and its center of sphere is heavy with the center of rotation of the acetabulum and femur. In the related art, usually, the ball center of the femoral head is obtained by fitting multiple data points on the acetabular side. However, in the related art, it is necessary to locate the region of the acetabulum in the pelvis. Since the situation of the region of the acetabulum is complicated, manual extraction is required, which causes a pr...
