PURPOSE:To make possible the quantitative grasping of symmetrical internal organs, etc. by indicating a contour image of a photographed body overlapped with a tomographic image. CONSTITUTION:A radiant ray from a radiatnt isotopic chemical contained in the internal organs of a photographed body 1, etc. is detected by a scintillation camera which moves around the photographed body 1 with the assistance of a rotary frame 20, and a tomographic image signal in each direction of the internal organs 11 is generated from a tomographic composition circuit 21. In the meantime, a contour image signal of the photographed body 1 is formed by a luminating and a light receiving device 3, 4 and a contour image composition circuit 43, etc. which likewise rotate with the help of the frame 20. The tomographic images of internal organs and the contour of a photographed body are displayed overlapped on a display unit. Thus it is possible to make possible easy and certain quantitative grasping of the position of internal organs, etc. |
