<；P>；PROBLEM TO BE SOLVED: To display a region to be imaged on an MRI image always clearly. <；P>；SOLUTION: A control part 17 determines the region to be imaged including a plurality of voxels on an image for positioning. The control part 17 superimposes and displays both the imaged region line expressing the region to be imaged and a grid line expressing the voxels on the image for positioning if the direction of slicing of the determined region to be imaged and the direction of slicing of the image for positioning are parallel or perpendicular to each other, or superimposes and displays only the imaged region line on the image for positioning if the two directions of slicing are neither parallel nor perpendicular to each other. <；P>；COPYRIGHT: (C)2008,JPO&INPIT
