Location And Marking Of MRI Spine Images

At present,vertebral disease is a very common disease,and MR images for the human spine has a very good imaging effect,for the diagnosis of spinal disease diagnosis,has a very important clinical significance,and vertebral positioning and labeling is the diagnosis and Critical steps in treatment.Traditional methods of vertebral labeling need to be manually marked on each of the vertebral blocks,and each vertebral block is measured.This manual positioning method is very complex and very time-consuming.So the use of computers to automatically locate and mark the spine to assist in the diagnosis of spinal disease has a very important practical significance.The study of this article is mainly on the MR full vertebral sequence images of disc automatic identification,and to achieve the automatic labeling of the vertebral function.The study is mainly divided into three parts,first by dividing the spinal cord to initially locate the position of the spine in an image;followed by the automatic identification of the disc;finally based on the identification of the results to find all the vertebral body,from top to bottom on the cervical spine,Thoracic vertebrae,lumbar spine a total of 24 vertebral block to mark.In this paper,the AdaBoost algorithm is used to identify the intervertebral disc.As the pixel information and edge information of the disc are more obvious,the pixel information and edge information of the intervertebral disc are extracted,and the corresponding Haar feature is extracted,and then the classifier is trained.Using the classifier to identify the disc on the sagittal pattern,locate the approximate position of the disc.And then according to the location of the disc information and gray distribution,to find the location of the spine.So far,find all 23 discs and 24 spine blocks and label them.In this paper,we can realize the localization function and vertebral label function of MR images in T1 and T2 modes.The experimental results show that the method can realize the positioning of the disc and the labeling function of the vertebral body.
