Abstract

The invention discloses a spine X-ray image processing method and system. The method includes utilizing a second spine X-ray image to perform rectification on a first spine X-ray image and obtain space conversion information of the first spine X-ray image; acquiring second coordinate information of rectified predetermined points according to the space conversion information and first coordinate information at least a pair of predetermined points on the edges of a spine in the first spine X-ray image; calculating and outputting the amount of spine deformation by utilizing the second coordinate information. According to the method and device, the amount of spine deformation can be calculated automatically according to the predetermined spine X-ray images and the coordinate information of a plurality of points inside, influences on calculation results by manual operation can be reduced, and the calculation results can be more accurate.

Description

technical field [0001] The invention relates to medical image processing technology, in particular to a method and system for processing spinal X-ray images. Background technique [0002] Spinal deformation, such as kyphosis, scoliosis, etc., early detection can prevent the further development of deformation. The deformation of the spine can be seen from the X-ray images of the spine, and quantitative measurement of the X-ray images of the spine can determine whether the deformation of the spine exceeds the normal range. [0003] At present, some manual and semi-automatic techniques have been used to quantitatively measure spinal deformation in X-ray images. Users need to manually mark the edges of the most inclined vertebral bodies at both ends of the spinal curve in X-ray images, and even manually determine the vertebral body edge curves. The tangent to calculate the deformation. These manual and semi-automatic methods require a lot of manual operations by users, resulti...
