摘要： In order to provide a technique for accurately realizing an examination, which is for acquiring a plurality of images of the same examination section, without a complicated operation and an extension of an examination time, body movement information of a subject is acquired immediately before each imaging in an examination, and it is determined whether or not there is a change in the position of the subject by comparing it with body movement information immediately before reference imaging. Only when there is a change in the position of the subject, an imaging slice setting image is acquired again. Then, a recommended imaging slice is calculated using the newest imaging slice setting image.

摘要： A magnetic resonance imaging apparatus is configured to divide an object to be examined into a plurality of regions in a predetermined direction, set images of slice positions for each of the regions so that the slice positions are continuous in each region, obtain an image of each of the regions while moving the object stepwise, and acquire a plurality of image data having three types of categories for the region, the slice position and the imaging sequence. The magnetic resonance imaging apparatus selectively sets one of the three types of categories and rearranges and displays a plurality of images having the set category in the lengthwise direction or the lateral direction according to the two other categories that have not been selectively set.
