Embodiment 1

[0044] The method for detecting the center of rotation of the femoral head in children comprises the following steps:

[0045] Step 1: Randomly select children's patient data in the orthopedic clinic of the Children's Hospital, and obtain CT images of the femoral head;

[0046] Step 2: Randomly select children between the ages of 6 and 12 from the orthopedic clinic to take CT images, and divide the detection objects into three groups of areas according to the age of the children, and divide the children in the three groups of areas Take CT images according to the following conditions, respectively mark the CT images into slices, and measure the vertical height and horizontal distance between the center of the bilateral acetabulum and the lower edge of the teardrop;

[0047] Step 3: Set the acetabulum as the origin of the center, connect a straight line between the teardrops on both sides, name the line segment as the line between teardrops, draw a vertical line from the center...

Abstract

The invention discloses a children caput femoris rotation center detection method, which comprises the following steps of: 1, randomly extracting data of a children patient in an orthopedic outpatient service of a pediatric hospital, and calling a caput femoris CT (Computed Tomography) image sheet; step 2, randomly selecting children of which the age range is 6-12 years old from an orthopedic outpatient service to take CT images, and dividing detection objects into three groups of area ranges according to the age condition of the children, according to the method, the vertical height average value and the horizontal distance average value of the acetabulum center in the femoral head images of the child patients in different age ranges are compared with the vertical height average value and the horizontal distance average value of the acetabulum center of a normal child, the deviation value range between the values is observed, and the acetabulum center of the normal child is determined according to the deviation value. And the caput femoris rotation center deviation conditions of the child patients in different age ranges and stages can be screened out, so that subsequent treatment on the child patients in different age stages is facilitated.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a method for detecting the rotation center of a child's femoral head. Background technique [0002] Developmental dysplasia of the hip, 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. 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, the loss of the concentric circle relationship of the head socket in children with DDH leads to a series of morphological changes in the hip joint. The parameters that define DDH and its severity include acetabular index, Perkin quadrant, central margin angle, Shenton's line, acetabular ...
