PROBLEM TO BE SOLVED: To provide a technology capable of detecting the existence/absence of body movements during imaging without the extension of imaging time in DWI measurement for performing MPG application multidirectionally by a magnetic resonance imaging device.SOLUTION: A plurality of image groups being six or more selected from a plurality of diffusion weighted images are created so as to make one or more included diffusion weighted images different S401. A value of a predetermined diffusion index representing the feature amount of the diffusion weighted images is calculated in each image group from the diffusion weighted images included in the image group S402. A value of a predetermined body movement index about body movement information is calculated from the value of the diffusion index of each image group S403. The existence/absence of body movements is determined in each image group on the basis of the value of the body movement index S404.SELECTED DRAWING: Figure 4 |
