A spatial rendering method and system for brain nerve fibers

Abstract

The invention provides a space drawing method of cranial nerve fibers and a system adopting the space drawing method of the cranial nerve fibers. The system comprises (1) a data management and preprocessing module, (2) a cranial nerve fiber color mapping module, (3) a cranial nerve fiber space drawing module and (4) a cranial nerve fiber space searching and interaction module, wherein the data management and preprocessing module has functions of data importing, modeling and cranial nerve fiber path tracking; the cranial nerve fiber color mapping module has the basic step of using the cranial nerve fiber color for representing the space direction field information, i.e., a direction vector between two adjacent nodes on the cranial nerve fibers is calculated and is mapped to a color space; for the cranial nerve fiber path tracking result, a group of node sequences is used for representing one cranial nerve fiber, and the cranial nerve space drawing module sequentially connects one group of tiny linear segments for fitting a whole cranial nerve fiber curve; and the cranial nerve fiber space searching and interaction module calculates a space extreme value of the cranial nerve fiber data for determining the origin of a coordinate system center of a drawn scene and builds a space interaction mode based on a scene coordinate system.

Description

technical field [0001] The invention relates to the research of cranial nerve fibers, and relates to a method and system for spatial rendering of cranial nerve fibers. Background technique [0002] Diffusion-weighted magnetic resonance imaging (DW-MRI) technology can non-invasively track the structure of white matter nerve fibers, and provide important information for the study of white matter and the exploration of brain connectivity. Its fiber tracking imaging uses the diffusion effect of white matter water molecules to track and reconstruct the three-dimensional structure of white matter fiber bundles, and can visually display the direction of white matter nerve fibers, which has attracted the attention of relevant researchers. [0003] The diffusion tensor imaging (DTI) method estimates the probability distribution of the diffusion direction of water molecules to track the fiber direction. However, when multiple fibers cross through a voxel, the DTI method cannot fully ...

Problems solved by technology

On the other hand, the space vector field information of brain nerve fibers cannot be directly converted into color information, which will cause misunderstandings and is not conducive to the space exploration of brain nerve fibers
