<p>In order to be able to easily acquire a color FA image in which the same fibrous tissue has the same color display even if images are captured in a state in which the position of a subject relative to an MRI device is different, diffusion tensor is configured using a plurality of sets of the diffusion-weighted image data acquired by capturing images of a site including the fibrous tissue of the subject, a specific vector is found from the diffusion tensor, the specific vector represented by a predetermined first coordinate system is transformed into a second coordinate system, and an image representing the running direction of the fibrous tissue is acquired on the basis of the components of the specific vector represented by the second coordinate system. The second coordinate system is found preferably on the basis of the imaging cross section, or on the basis of the specific vector for the specified pixel in the image acquired by capturing images of the imaging cross section, or in accordance with the rotation angle of the coordinate system set by a coordinate system rotation (UI).</p> |
