With regard to images acquired by administering a contrast agent multiple times, and each time causing an imaging region to move, the present invention reduces the difference in the shape and size of tissue depicted in the images, reduces the effects of residual contrast agent, and of recirculation, and performs perfusion analysis on the images that do not specify an artery region. The present invention comprises a medical imaging analysis device which has an image capture unit, a calculation unit, and an analysis unit. The image capture unit divides a region that includes a subject object to be imaged into multiple subregions, and while providing an overlap region in which the multiple subregions overlap, administers the contrast agent to each of the subregions, and acquires multiple time series images. On the basis of the pixel value shift of one time series image, which is among the multiple time series images, and includes the overlap region, the calculation unit calculates the pixel value shift of the other time series images that include the overlap region. The analysis unit determines the blood flow state of the subject by analysing the time series images on the basis of the pixel value shift of the one time series image, and the pixel value shift of the other time series images. |
