NERVE-FIBER BUNDLE MEASURING SYSTEM AND IMAGE PROCESSING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a measuring system or image processing system capable of quantitatively recognizing fiber bundles passing through an arbitrary observation area. SOLUTION: A static magnetic field and high-frequency signals are applied to a subject and nuclear magnetic signals from the subject are received (401). The diffusion tensor is calculated from the nuclear magnetic signals (402). Fiber bundles passing by a plurality of prescribed starting points are extracted as groups of coordinate points for the respective fiber bundles based on the diffusion tensor calculated by a calculating part in the target range for receiving the nuclear magnetic signals of the subject (406). At least one observation area is set for the target range for receiving the nuclear magnetic signals (408). The fiber bundles with at least one of the coordinate point groups included in the observation range are discriminated from the plurality of fiber bundles extracted by a fiber bundle extracting part and are counted (409).
