Embodiment 1

[0054] The present embodiment 1 provides the method for using the device for predicting the risk of femoral head collapse, including the following steps:

[0055] (1) Import the case hip joint CT file (di com format) into the image separation unit, use Mimics medical image processing software to process, separate the mask of the proximal femur based on the gray value segmentation, and reconstruct the three-dimensional model of the proximal femur;

[0056] (2) With the plane of the base of the femoral head as the boundary, separate the three-dimensional model of the femoral head from the three-dimensional model of the proximal end of the femur;

[0057] (3) In the analysis unit, calculate the Polyline of the three-dimensional model of the femoral head, and then reconstruct the femoral head mask based on the Polyline;

[0058] (4) Using the image separation unit in the original hip joint CT file, based on the gray value segmentation, separate the sclerotic bone mask, cancellous ...

Embodiment 2

[0065] According to the method provided in Example 1, the original CT images of 50 cases (28 males and 22 females, with an average age of 38.12±10.14 years, 50 hips in total) were reviewed in this example.

[0066] Among them, the 50 cases were divided into a collapse group and a non-collapse group with 25 hips each; 5 healthy volunteers (5 hips) were recruited as healthy controls.

[0067] (1) The original CT images of each case were imported into Mimics medical image processing software for morphological analysis, based on the gray value segmentation, the mask of the proximal femur was separated, and the three-dimensional model of the proximal femur was reconstructed; with the base plane of the femoral head as the boundary, In the 3D model of the proximal femur, separate the 3D model of the femoral head;

[0068] figure 1 The reconstructed 3D model of a case is given in , where A is the 3D model of the proximal femur, and B shows the plane of the base of the femoral head, a...

Abstract

The invention provides a device for predicting the femoral head collapse risk and a using method and application thereof. The device comprises an image processing unit, an analysis unit, a separationunit, a calculation unit and an output unit. The device can obtain a plurality of data of the femoral head of a case according to the hip joint CT image of the case, wherein the data comprises hardened bone volume, soft tissue volume and total head bone density; the relation between each data and the disease course time of the case is obtained simultaneously, and the femoral head collapse risk ofthe case is calculated according to the total head bone density and the hardened bone volume of the case, thereby providing reliable medical data for clinical treatment of femoral head necrosis.

Description

technical field [0001] The present invention relates to the technical field of medical image recognition, in particular to a device for predicting the risk of femoral head collapse, its use method and application. Background technique [0002] Osteonecrosis of the femoral head (ONFH), also known as avascular necrosis (AVN), refers to the local blood circulation disorder in the femoral head caused by various reasons, resulting in bone cell hypoxia, shrinkage and die. Femoral head necrosis is a pathological evolution process, which initially occurs in the load-bearing area of ​​the femoral head. Under the action of stress, the trabecular structure of the necrotic bone is damaged, that is, microfracture, and the subsequent repair process for the damaged bone tissue. If the cause of osteonecrosis is not eliminated, the repair is not perfect, and the process of injury and repair continues, resulting in changes in the structure of the femoral head, collapse, deformation, arthriti...
