Problems solved by technology

[0003] So far, there is only one patent on spinal cord segmentation in China - the patent "A Spinal Cord Segmentation Method Based on Convex Constrained Seed Region Growth" invented by Long Jianwu of Chongqing University of Technology and others, which is similar to the existing papers on spinal cord segmentation Similarly, the invention patent process is also more complicated
[0004] In summary, the existing technology obviously has inconvenience and defects in actual use, so it is necessary to improve

Abstract

The invention relates to the technical field of medical images, in particular to an automatic spinal cord segmentation method and system based on a medical image. The spinal cord automatic segmentation method and system based on the medical image comprises the steps that A, selecting an ROI of a spinal cord from the medical image; b, searching a circular spinal cord area of a first layer of imagein the ROI to segment spinal cords in the first layer of image; C, according to the circular spinal cord area of the first layer of image, searching the circular spinal cord area of the 2-N layer images in the area of interest to segment spinal cords in the 2-N layer images, wherein N is the number of image layers in the area of interest. Therefore, the segmentation calculation amount is reduced,and spinal cord segmentation speed is increased.

Description

technical field [0001] The invention relates to the technical field of medical images, in particular to an automatic spinal cord segmentation method and system based on medical images. Background technique [0002] Among the various organs and tissues of the human body, the spinal cord is a very important and sensitive organ. During radiation therapy, it is necessary to receive as little radiation dose as possible, otherwise it is easy to cause unpredictable neurological complications such as paralysis. For the spinal cord, at present, it is mainly to manually outline layer by layer images. Although there are some semi-automatic or fully automatic methods, the recognition rate is often low and the time is long due to the complexity of the automatic extraction of the entire recognition process, which cannot be used clinically. It has been well applied and recognized. Therefore, the automatic delineation of the spinal cord based on CT (Computed Tomography, computerized tomogr...
