Children femoral head rotation center detection method

Abstract

The invention discloses a children femoral head rotation center detection method, which comprises the following steps: acquiring and selecting children bilateral hip joint X-ray images, marking mark points, an X axis and a Y axis, and measuring hip joint indexes; processing hip joint indexes to obtain sample data and setting weights; dividing the data into a training set and a test set, training the detection model by adopting the training set, and detecting by adopting the test set to obtain a final children femoral head rotation center detection model; and detecting the femoral head rotationcenter of the bilateral hip joint X-ray image of the child to be detected by adopting the final child femoral head rotation center detection model. The method can quickly and accurately detect the rotation center of the caput femoris of the child, and is high in training speed, high in stability and good in practical effect.

Description

technical field [0001] The invention belongs to the field of image processing, and in particular relates to a method for detecting the center of rotation of a child's femoral head. Background technique [0002] With the development of economy and technology and the arrival of the intelligent age, image processing technology and artificial intelligence technology are being widely used in the fields of health examination and medical treatment, bringing endless convenience to people. [0003] Developmental dysplasia of the hip (DDH), also known as developmental dislocation of the hip, is a clinically common childhood hip disease, usually including acetabular dysplasia, subluxation of the femoral head and total dislocation of the femoral head Wait. The concentricity of the head socket (that is, the center of rotation of the femoral head maintains a concentric circle relationship with the center of the acetabulum) is a prerequisite for the development of the hip joint. However, ...

Problems solved by technology

Also due to insufficient ossification of the epiphysis of the femoral head and the presence of more cartilage, on anteroposterior X-ray images of the hip joints of young children, the ossification of the epiphysis of the femoral head is insufficient and does not form a standard semicircle, and even the epiphysis of the femoral head The center of the femoral head often deviates from the center of rotation

In this case, according to the previous method, use the anatomical landmarks and anatomical meridians on the anteroposterior X-ray image of the hip joint, or use the center of the epiphysis of the femoral head to locate the rotation center of the femoral head, and judge the relationship between the femoral head and the hip joint. There may be a certain deviation in whether the acetabular relationship is restored to the concentric circle, which will further mislead and affect subsequent treatment decisions
