Cerebral cortex surface reconstruction method and readable storage medium

Abstract

The invention discloses a cerebral cortex surface reconstruction method and a readable storage medium, and belongs to the field of medical image processing. The cerebral cortex surface reconstruction method comprises the following steps: performing data preprocessing on a medical image to obtain a standardized image; inputting the standardized image into a segmentation model to segment a brain anatomical structure adjacent to gray matter so as to obtain a distinguished brain anatomical structure segmentation image; inputting the distinguished brain anatomical structure segmentation image and the standardized image into a surface level set prediction model to obtain a level set representation image of an interface between the brain anatomical structure and the grey matter; the level set representation image of the interface between the brain anatomy and the grey matter is input into a topological repair module and a polygonal mesh representation reconstruction module to obtain a polygonal mesh representation of the interface between the brain anatomy and the grey matter.

Description

technical field [0001] The invention relates to the field of medical image processing, in particular to a cerebral cortex surface reconstruction method and a readable storage medium. Background technique [0002] In recent years, since the reconstruction of the cerebral cortex surface based on magnetic resonance imaging (MRI) is helpful for the research of neuroscience and the clinical diagnosis of neurodegenerative diseases, the visualization and cortical analysis of the cerebral cortex can be completed using the reconstructed cerebral cortex surface. Morphometry can also enable cortical surface-based analysis methods in functional magnetic resonance imaging applications, such as brain functional network analysis methods, and so on. [0003] Although the existing cerebral cortex surface reconstruction technology can reconstruct a relatively reliable cerebral cortex surface, in order to achieve a high accuracy of the reconstructed cerebral cortex surface, a large amount of c...
