    摘要: The present invention provides a measurement system and an image processing system for quantitatively figuring out the fiber bundles which are passing through any VOI. A static magnetic field and an RF signal are applied to a subject, and a nuclear magnetic resonance signal is received from the subject (401). Diffusion tensor is calculated from the nuclear magnetic resonance signals (402). As to a target area for receiving the nuclear magnetic resonance signal from the subject, fiber bundles passing through multiple predetermined origins, respectively, are extracted in a form of a group of coordinate points for each of the fiber bundles, based on the diffusion tensor calculated by the calculating means (406). At least one VOI is set for the target area for receiving the nuclear magnetic resonance signal (408). Out of the multiple fiber bundles extracted by the fiber bundle extracting means, the fiber bundles having at least one coordinate point of the group of coordinate points being included in the VOI are discriminated and the number of which is counted (409).
