Intervertebral disc section image construction method and device, computer equipment and storage medium

Abstract

The embodiment of the invention belongs to the field of artificial intelligence, and relates to an intervertebral disc section image construction method, which comprises the steps of obtaining three-dimensional image data of a lumbar vertebra; extracting intervertebral disc region data in the three-dimensional image data; performing principal component analysis on the intervertebral disc region data to obtain an orthogonal coordinate system of the intervertebral disc region data; constructing a reconstruction plane according to the orthogonal coordinate system; calculating a rotation matrix between the reconstruction plane and the horizontal plane; constructing plane point cloud data of a horizontal plane, and multiplying the plane point cloud data by the rotation matrix to obtain projection data of the plane point cloud data on a reconstruction plane; obtaining a gray value corresponding to the projection data in the three-dimensional image data; and constructing a section image of the intervertebral disc according to the projection data and the gray value. The invention further provides an intervertebral disc section image construction device, computer equipment and a storage medium. According to the method, principal component analysis is carried out on the intervertebral disc region data, so that the accuracy of the constructed intervertebral disc section image can be improved.

Description

technical field [0001] The present application relates to the technical field of artificial intelligence, in particular to a method, device, computer equipment and storage medium for constructing a cross-sectional image of an intervertebral disc. Background technique [0002] In the field of medical images, cross-sectional images of intervertebral discs have always been an important branch, which has high medical value. The more common way to obtain cross-sectional images of intervertebral discs today is: first take a three-dimensional CT image of the lumbar spine, and then operate the software to manually intercept the cross-sectional images of the intervertebral discs to be observed or automatically intercept the cross-sectional images of the intervertebral discs by the software. When the software automatically intercepts the cross-sectional images of the intervertebral disc, the software usually uses a more mechanical interception method. If the lumbar curvature is encoun...
