1. A medical imaging analyzer comprising processing circuitry configured to: divide an area including an object of a subject to be captured into a plurality of partial areas such that the partial areas overlap each other to form an overlapping area, and administer a contrast agent to each of the partial areas to capture a plurality of time-series images; calculate, based on a transition in pixel value in one of the time-series images having the overlapping area, a transition in pixel value in another of the time-series images having the overlapping area; and analyze the time-series images based on the transition in pixel value in the one and the other of the time-series images to obtain hemodynamics of the subject.
