PROBLEM TO BE SOLVED: To provide an inexpensive Compton camera, capable of being miniaturized, with high resolution by three-dimensionally grasping the incident position of incident radial rays (for example, gamma rays).SOLUTION: A Compton camera 1 includes: a scattering detection section 10; an absorption detection section 20; and a signal processing section 30. The scattering detection section 10 includes: a light reception section 11; a light reception section 12; and a scintillator block 13. The absorption detection section 20 includes: a light reception section 21; a light reception section 22; and a scintillator block 23. Each scintillator block generates scintillation lights in accordance with the Compton scattering or absorption of radial rays, and selectively propagates the scintillation lights in a -z direction and a +z direction, and outputs the scintillation lights to the outside. The rates of the external output intensity of the scintillation lights in the respective -z direction and +z direction are set different from each other in accordance with the generation positions of the scintillation lights. Each light reception section receives the scintillation lights output from each scintillation block, and outputs an electric signal showing the light reception position and the light reception intensity on the light reception surface to a signal processing section 30. |
