Spine Cobb angle measurement method and device, readable storage medium and terminal equipment

Abstract

The invention belongs to the technical field of image analysis, and particularly relates to a spine Cobb angle measurement method and device, a computer readable storage medium and terminal equipment.The method comprises the steps of using a pre-trained deep learning network model for carrying out segmentation processing on a spine X-ray image to acquire a segmentation result image, wherein the segmentation result image is a binary image of a spine area and a non-spine area; respectively identifying each spine block from the spine area of the segmentation result map; determining upper and lower end plate straight lines of each spine block; traversing calculation is conducted on the upper end plate straight line and the lower end plate straight line of each spine block, wherein the included angle with the maximum value is determined as the spine Cobb angle. According to the embodiment of the invention, automatic measurement of the spine Cobb angle is truly realized, the required spineCobb angle can be obtained without additional operation of a worker, errors caused by manual or semi-manual measurement of the spine Cobb angle are avoided, and better reliability is achieved.

Description

technical field [0001] The invention belongs to the technical field of image analysis, and in particular relates to a spine Cobb angle measurement method, device, computer-readable storage medium and terminal equipment. Background technique [0002] The traditional method of measuring the Cobb angle of the spine is manual measurement on the X-ray film by the staff using a pencil and a protractor. like figure 1 As shown, in the process of measuring the Cobb angle, the staff find out the end vertebra with the largest inclination through experience, and the scoliosis will roughly show three curves, and the one with the largest degree of curvature is the Cobb angle. Because this method is performed manually, there is some error and its intra-observer and inter-observer reliability is poor. This method requires manual drawing of the extension of the endplate and then making a vertical line and measuring with a protractor. These manual operations have brought various errors, cau...
