    摘要: In a gamma camera, a plurality of radiation detector elements having a rod-shaped first electrode, a semiconductor device surrounds the first electrode to contact with it for entering a radiation, and a second electrode provided for the side surface of the semiconductor device are detachably attached to a holding member. The holding member has a first electrode contact portion contacted with the first electrode and a second electrode contact portion contacted with the second electrode. A collimator in which a plurality of radiation paths provided corresponding to the plurality of radiation detector elements are formed is arranged on the radiation entering side of the plurality of radiation detector elements. A γ-ray detection signal outputted from the first electrode contact portion is sent to a signal processing integrated circuit. A high voltage is applied to the second electrode via the second electrode contact portion.

    摘要: A γ-ray signal processing section 60′ determines a detection time of a γ ray based on a α-ray detection signal outputted from a semiconductor radiation detector for detecting the γ ray, and determines the energy of the γ ray. Then, a time correction circuit 70 obtains, based on the energy of the γ ray, a detection value of the detection time that corresponds to the energy of the γ ray from a time correction table indicating the relationship between the energy of the γ ray and the correction value of the detection time of the γ ray, and corrects the detection time according to the obtained correction value of the detection time. Coincidence counting is performed on the γ ray in a coincidence counting circuit 80 based on the corrected detection time.
