MAGNETIC RESONANCE APPARATUS WITH IMAGE-BASED POSITION DETECTION OF A PART TO BE DETECTED

摘要

To minimize an error in detecting the position of a part to be detected (for example, an uppermost end of the liver) as much as possible. The MR apparatus 100 comprises: image producing unit 9a for producing coronal images of a part to be imaged; search-region defining unit 9d for defining a region Rs 1 to be searched; unit for determining an indicator VI representing a likelihood that a pixel contained in the region Rs 1 to be searched lies on an edge E of a liver adjacent to lungs; and unit for, by dividing the region Rs1 to be searched into a plurality of sub-regions R1— R11 arranged in an Si-direction, determining a position of the edge E of the liver in the SI-direction based on indicators VI obtained on a sub- region-by-sub-region basis.
