Abstract

The invention discloses a proximal femoral medullary cavity image data processing method and device, equipment and a storage medium. The method comprises the following steps: inputting a to-be-segmented two-dimensional CT medical image into an image segmentation network model obtained by pre-training to obtain a body surface projection image and an X-ray projection image of a thighbone position area; based on the body surface projection image of the femur position area, determining position coordinates of a femur lesser trochanter, and according to the position coordinates of the femur lesser trochanter and the X-ray projection image of the femur cortex area, determining the femoral metaphysis width and the femoral marrow cavity isthmus diameter of the femur position area; and calculating a femoral medullary cavity flicker index according to the diameter ratio so as to determine the type of the femoral medullary cavity form. Accuracy of the femoral metaphysis width and the femoral isthmus diameter is improved, so that the calculation accuracy of the femoral marrow cavity flicker index is improved, and an operator can be well helped to carry out pre-operation planning, such as selection of a femoral stem prosthesis in a joint replacement operation.

Description

technical field [0001] The present application relates to the technical field of medical devices, in particular, to a method, device, device and storage medium for image data processing of the proximal femoral medullary cavity. Background technique [0002] In joint replacement surgery, the type and placement angle of the prosthesis are determined through preoperative planning. For example, the type of the femoral stem prosthesis needs to be determined according to the specific shape characteristics of the femur. Usually, the femoral shape classification is performed by calculating the scintillation index of the femoral canal, and the result of the femoral shape classification is a key factor in the selection of femoral stem prosthesis in joint replacement surgery. [0003] In the related art, the calculation of the scintillation index of the femoral medullary cavity is usually done manually, based on experience, with large subjective factors and relatively large errors. C...
