Abstract:
1. A radiological imaging apparatus comprising: a radiation source for irradiating a radiation while moving around a bed; a radiation detection apparatus comprising a plurality of radiation detectors arranged around said bed and in a longitudinal direction of said bed, wherein said radiation detection apparatus comprises a γ-ray detection portion arranged in said longitudinal direction of said bed for outputting a γ-ray detection signal of a γ-ray having an energy which is different from that of a radiation irradiated from said radiation source and a radiation detection portion for detecting a radiation irradiated from said radiation source and outputting a radiation detection signal, each of said γ-ray detection portion and said radiation detection portion including at least one of said radiation detectors; and a radiation source moving apparatus for moving said radiation source in said longitudinal direction, wherein at least a part of said radiation detection portion is formed in an area between one end portion of said γ-ray detection portion and the other end portion of said γ-ray detection portion in said longitudinal direction of said bed.
