Problems solved by technology

However, because the boundary line between the femoral head and the acetabulum is not obvious in the CT images of the hip joint sequence, ordinary CT image segmentation algorithms cannot accurately segment the outline of the region from the femoral head to the femoral neck (i.e., the outer boundary of the bone cortex). Affect the implementation of programs such as artificial joint replacement

Abstract

The invention discloses a femoral head region segmentation method in a CT image, a segmentation device and equipment. The method comprises steps: a CT sequence image for an inspected body femoral headregion is acquired; through positioning a femoral head region in each image of the CT sequence image, a femoral head surrounding box and a femoral neck surrounding box are constructed; based on a space radiant line method, multiple sampling points are acquired in the femoral head surrounding box and the femoral neck surrounding box; a two-dimensional sampling image is generated according to the multiple sampling points; and a cortical bone outer boundary of the femoral head region is determined on the two-dimensional sampling image. Thus, the cortical bone outer boundary of the femoral head region in the CT sequence image can be segmented accurately, and a basis is provided for implementation of follow-up artificial joint replacement and other schemes.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method, device and equipment for segmenting a femoral head region in a CT image. Background technique [0002] Artificial joint replacement is one of the important methods for the treatment of hip joint diseases. Before performing artificial joint replacement, it is necessary to select an artificial femoral head that matches the patient's own joint. The existing technical solution is to perform feature extraction on the region from the femoral head to the femoral neck, and then perform data mining based on the extracted features to estimate the characteristics of the patient's femur before the lesion, and then select a matching artificial femoral head to ensure the progress of the operation. . In order to accurately extract the features of the region from the femoral head to the femoral neck, it is necessary to accurately segment the region from the femoral h...
