PURPOSE:To obtain an image at every combination of phases of two or more periodic vital movements immediately upon finish of data collection and to make a time for edition completely needless by collecting a visual information of a living body at every combination of those phases in an image mode. CONSTITUTION:In case that an RI image of heart is obtained at its every phase and at every phase of respiration, a scintillation camera 2 is pointed to a subject 1, and a radiation from an RI, which is dosed into the subject's body and accumulated in its heart, is caught by the scintillation camera 2. An information of incident position of radiation at every incidence is stored into a storage device 4 from the scintillation camera 2 through a data collection control device 3. On the other hand, an electrocardiograph 5 and a respirometer 7 are set to the subject 1 and detections of electrocardiogram and respiratory wave are carried out at the same time. A timing generation device 6 catches, for example, R wave of the electrocardiogram, generates a timing signal and send it to the data collection control device 3. The respiratory wave from the respirometer 7 is also sent to this data collection control device.
