SYSTEMS AND METHODS FOR OBJECTIVE TRACTOGRAPHIC PROCESSING USING FEATURES OF GRID STRUCTURES OF THE BRAIN

摘要

A system and method includes acquiring image data of the subject that includes information about the white matter tissue in the brain of the subject having diffusion information. An image of the subject is reconstructed from the image data that depicts the white matter tissue. A coordinate system information is produced by correlating the white matter tissue in the reconstructed image with a coordinate system in which the white matter tissue is arranged in an orthogonal grid. A deviation of the white matter tissue from the orthogonal grid is determined. Fiber paths of the white matter tissue are built by applying a bias against information determined to be associated with a deviation of the white matter tissue from the orthogonal grid.

1. A method for processing of an image of a subject, the steps of the method comprising:
a) acquiring image data of a subject that includes white matter tissue containing white matter fibers, the image data being sensitized to diffusion; b) identifying, using image data, intersecting white matter fibers extending in a two-dimensional (2D) plane; c) determining a deviation for each of the intersecting white matter fibers from the 2D plane; d) comparing the deviation for each of the intersecting white matter fibers from the 2D plane to a tolerance; e) building an orthogonal grid of intersecting white matter fibers that extend in the 2D plane and is within the tolerance of step d); and f) generating an image of the white matter fibers of the subject using the orthogonal grid.
