The processing circuitry acquires a plurality of pieces of medical image data arranged in time series over at least one cardiac cycle in which a region including a pulsative target of a subject is imaged. The processing circuitry performs a plurality of motion estimation processes using a pattern matching at frame intervals different from each other on an identical position for the pieces of medical image data and determines most likely second motion information from among a plurality of pieces of first motion information estimated by the motion estimation processes. | 2021-12-16 |
