Abstract

The invention provides an individualized structure connection brain atlas drawing method based on a diffusion magnetic resonance imaging fiber bundle tracking technology. A group probabilistic brain atlas based on cerebral cortex structure connection is used as a priori starting point, and iterative optimization is performed at the individual brain level according to the structure connection information of the local cortex of the individual brain so as to generate a spatial division mode of the individualized brain region. The method is suitable for drawing and analyzing the individualized brain atlas by utilizing diffusion magnetic resonance imaging.

Description

technical field [0001] The invention relates to a method for drawing an individualized structural connection brain atlas according to brain connection characteristics by using a non-invasive brain imaging method, and belongs to the technical field of cognitive neuroscience. Background technique [0002] At present, the inter-individual differences in brain anatomical structure and function are gradually being paid attention to. An important issue in the field of cognitive neuroscience and clinical medicine is to build an individualized brain map. The human brain exhibits significant interindividual variability in many aspects, including macroscopic and microscopic brain anatomy. In neuroscience research, if the group brain atlas is directly used as an individual brain region division model, the deviation of brain region division will be introduced due to individual differences, which will affect the research and analysis of brain structure and brain function. At the same ti...
