Abstract

An image processing apparatus according to an embodiment includes processing circuitry (9070). The processing circuitry (9070) is configured to acquire list-mode data corresponding to a plurality of detection times, generate a plurality of frames based on the list-mode data, assign at least one frame of the plurality of frames into a first frame group based on a similarity of each frame, assign at least one frame of the plurality of frames into a second frame group based on a similarity of each frame, estimate first and second frame group-specific reconstruction parameters based on frames in first frame group, and frames in the second frame group, respectively, wherein the first and second frame group-specific reconstruction parameters are different, reconstruct a first set of frame data from any frame of the first frame group based on the first frame group-specific reconstruction parameter, and reconstruct a second set of frame data from any frame of the second frame group based on the second frame group-specific reconstruction parameter.
