Method, system, apparatus and storage medium for measuring neck shaft angle in pelvic X-ray film

Abstract

The invention provides a method, system, apparatus and storage medium for measuring neck shaft angle in pelvic X-ray film. The method for measuring neck shaft angle in pelvic X-ray film comprises thefollowing steps: acquiring X-ray film image including pelvis; Detecting a femoral shaft region and a femoral neck region in the X-ray image; Extracting a longitudinal axis of a femoral shaft from thefemoral shaft region and extracting a short axis of a femoral neck from the femoral neck region; obtaining the neck shaft angle according to the longitudinal axis of the femoral shaft and the short axis of the femoral neck. The invention can accurately and efficiently automatically measure the neck shaft angle in the pelvic X-ray film, and effectively solves the problem in the prior art that theneck shaft angle in the X-ray film is easy to misjudge by relying on the subjective observation of the medical personnel or the hand drawing method, which is time-consuming and laborious.

Description

technical field [0001] The invention belongs to the technical field of image processing, in particular to the technical field of X-ray film image processing, and specifically relates to a method, system, device and storage medium for measuring neck-shaft angles in pelvic X-ray films. Background technique [0002] The neck-shaft angle is the angle formed between the long axis of the femoral neck and the longitudinal axis of the femoral shaft, also known as inclination. The normal value is between 110-140 degrees, with an average of 132 degrees for men and 127 degrees for women. A neck-shaft angle greater than normal indicates coxa valgus, and a value less than normal indicates coxa varus. The neck-shaft angle is an important indicator for the diagnosis of hip dysplasia and impingement syndrome. In medical practice, medical staff often judge whether the neck-shaft angle is in the normal range by subjective observation on pelvic X-rays, or measure the value of the neck-shaft ...

AI Technical Summary

Problems solved by technology

[0004] In view of the shortcomings of the prior art described above, the purpose of the present invention is to provide a method, system, device and storage medium for measuring the neck-shaft angle in pelvic X-ray films, which are used to solve the problem of relying on the subjective observation of medical personnel in the prior art. Or judge the neck-shaft angle in X-ray film by hand, which is prone to misjudgment, time-consuming and labor-intensive problems
