Group brain map individualization method, system and equipment based on individual brain connection map

Abstract

The invention belongs to the field of image processing, particularly relates to a group brain map individualization method, system and equipment based on an individual brain connection map, and aims to solve the problem that an existing brain map function division mode is difficult to reflect differences among individuals and realize cross-individual analysis. The method comprises the following steps: acquiring a T1 weighted nuclear magnetic resonance image of a target and a dispersion nuclear magnetic resonance image of a to-be-detected target, extracting surface grid triangular nodes and edges of white matter and grey matter surface structures, taking a vertex of a grey matter and white matter interface as a node of the individual brain connection map, and taking a spatial neighborhood as an edge of the individual brain connection map, obtaining a fiber bundle fingerprint through the corrected diffusion MRI image, taking the fiber bundle fingerprint as a node attribute of the individual brain connection graph, and finally obtaining a partitioned individual level brain map through a brain region classification graph convolutional network. According to the method, the individualized brain map drawing process is established, and the robustness of individual difference drawing is improved by utilizing the fiber bundle connection fingerprints and the map convolutional network.

Description

Technical field [0001] The present invention belongs to the field of image processing, particularly relates to a group of individual brain atlas methods, systems and devices based on the individual's brain connector of FIG. Background technique [0002] Human cerebral cortex function can be divided into a plurality of specific regions having different characteristics in vivo and ex vivo. In order to understand the functional organization of the human brain, nerve anatomist was originally built to use some of the human brain, the cells were analyzed by building, myelination, receptor distribution and anatomy of various groups to create a drawing of a brain atlas. As technology advances, a magnetic resonance imaging (MRI) technology has been used to study living human brain characterized in brain (e.g., macro-structure, and the communication function is activated), thereby further explore the human genome maps. Although the population level may reflect the spatial distribution of c...
