Abstract

The invention discloses an image recognition and model training method and a true mortar position recognition method and device. The true mortar position recognition method comprises the steps of obtaining medical image data; performing image segmentation on the medical image data, and determining a femur area and a pelvis area based on an image segmentation result; performing multi-stage zooming processing on the image segmentation result, and determining the femoral head central point and the teardrop lower edge position of the uninjured side based on the image zooming result; and determining the position of the true mortar based on the caput femoris central point and the teardrop lower edge position of the uninjured side. According to the method, false acetabulum interference of DDH developmental dislocation of the hip joint can be rapidly eliminated, the position of the true acetabulum can be rapidly identified, an operator can conveniently place the acetabulum cup prosthesis at the position of the true acetabulum, and the preoperative planning efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a method for image recognition and model training, and a method and device for recognizing the position of a real socket. Background technique [0002] In the medical field, the preoperative planning of total hip replacement surgery mainly includes the calculation of the required prosthesis type and the position of the osteotomy line. The preoperative planning of total hip joint replacement surgery plays a very important role in the success rate of the operation. Currently, the main The method of preoperative planning is to manually measure through various tools to determine the specific location of the key parts that need to be operated on. This method is inefficient and the accuracy cannot be guaranteed. Therefore, how to quickly and accurately identify the key points in the image Location is a burning issue. Contents of the invention [0003] In view of this, the ...
