MRI spine image intervertebral disc scanning positioning and vertebra identification method based on deep learning

Abstract

The invention discloses an MRI spine image intervertebral disc scanning positioning and vertebra identification method based on deep learning. The method comprises the following steps of s1, performing semantic segmentation on a MRI spine image prepared in advance by using a convolutional neural network model; s2, fitting foreground pixels on the image obtained by semantic segmentation in the step s1 to obtain a plurality of polygons; s3, polygon screening is carried out; s4, polygon sorting is carried out, labels are added, and vertebra identification is completed; s5, polygon edge approximation is carried out, and the number of vertexes is reduced, so that the polygon is closer to a quadrangle; s6, calculating and finding out a lower left corner vertex, an upper left corner vertex, an upper right corner vertex and a lower right corner vertex of the polygon; and s7, calculating an intervertebral disc scanning positioning line to complete intervertebral disc scanning positioning. According to the invention, the efficiency of MRI spine examination can be improved, the manual workload is reduced, and the scanning positions of multiple examinations of a patient have very high repeatability.

Description

technical field [0001] The invention relates to the technical field of medical image processing, in particular to a deep learning-based MRI spine image intervertebral disc scanning positioning and vertebral identification method. Background technique [0002] With the improvement of the economic level and the development of technology, people have put forward higher requirements for medical and health care. Magnetic resonance imaging (Magnet Resonance Image, MRI) as an advanced imaging diagnostic technology is more and more widely used in the examination of patients. Compared with other imaging techniques, the use of MRI for the diagnosis of spine-related diseases has obvious advantages, such as more obvious tissue contrast, imaging in any direction, etc. [0003] In the process of MRI examination of the spine, there are two key operations, disc positioning and vertebral identification: [0004] Intervertebral disc localization refers to that after the MRI scanning positio...

AI Technical Summary

Problems solved by technology

[0009] 1. It takes a long time to manually perform the operation. It usually takes several minutes to perform the positioning operation manually for scanning a sequence of intervertebral discs;

[0010] 2. In the diagnosis of film reading, it is also very time-consuming to manually determine the vertebral label, and a lot of manual work is repeated, which is very easy to cause fatigue and lead to errors and misdiagnosis
