ABSTRACT:
A SPECT apparatus has a two-dimensional detector that detects radiations from RIs in a patient via a collimator. A correction processing unit corrects plural two-dimensional projection distributions with different projection angles, which are detected by the detector, on a three-dimensional frequency space according to plural correction functions corresponding to plural distances, respectively. Consequently, a fall in spatial resolution having dependency on distances between the respective RIs and the detector is reduced. A reconfiguring unit reconfigures a three-dimensional RI distribution from the plural two-dimensional projection distributions corrected.
