摘要： The radiological imaging system which can improve an energy resolution and perform a diagnosis with high accuracy includes a bed (14) for carrying an examinee H, first and second imaging apparatuses (1) and (4) disposed along the longitudinal direction of the bed (14). The first imaging apparatus (1) has a plurality of semiconductor radiation detectors (21) for detecting γ-rays emitted from the examinee H, arranged around the bed (14), the second imaging apparatus (4) has an X-ray source (45) for emitting X-rays to the examinee H and a radiation detector (40) for detecting X-rays which have been emitted from the X-ray source (45) and passed through the examinee H, and the bed (14) is shared by the first imaging apparatus (1) and the second imaging apparatus (4).
