Problems solved by technology

Specifically, this solution first requires manual intervention steps, requiring manual acquisition of the intervertebral disc area, and cannot achieve end-to-end operation of the entire algorithm
Secondly, the method gives the hu (housfield unit, HU) value based on the CT image, using the traditional method (PCA principal component analysis) to obtain several necessary measurements, (including a disc center, three main directions), based on the statistical method It is less effective than the method of directly using the segmentation mask to calculate

Abstract

The present invention provides a lumbar intervertebral disc observation surface positioning method, device and application applied to CT images. The coronal plane is obtained from the center point of the spine of the body, the coronal plane is corrected based on the positional relationship between adjacent lumbar vertebrae, and the observation plane of the lumbar intervertebral disc is obtained on the corresponding sagittal plane based on the positional relationship between adjacent lumbar vertebrae, which can realize end-to-end Automatic positioning of the lumbar intervertebral disc observation surface in lumbar CT images without human intervention.

Description

technical field [0001] The invention relates to the field of medical image processing, in particular to a method, device and application for locating a lumbar intervertebral disc observation surface applied to CT images. Background technique [0002] CT, electronic computed tomography, which uses precisely collimated X-ray beams, gamma rays, ultrasonic waves, etc., together with a highly sensitive detector to scan a certain part of the human body one by one, in order to obtain a clear human body. The cross-section or three-dimensional image of the inspected part has the characteristics of fast scanning time and clear image, which is of great significance in the detection of lumbar spine diseases. [0003] In other words, lumbar spine CT examination technology can be used for various lumbar spine diseases, such as spinal trauma, spinal stenosis of various causes, intervertebral disc degenerative disease and intervertebral disease herniation, etc. The acquisition of interverte...
