PURPOSE:To photograph a whole-body image and a tomographic image excellently in a short time by arranging two detectors, which have rectangular effective visual fields having long sides in the width direction of a top plate, opposite each other. CONSTITUTION:This camera consists of the top plate 24 where a body to be inspected is mounted, a movable indication stand 10 which has an opening part in the center, and the detectors for gamma rays from the body to be inspected, and the detectors are rotated and moved around of the body to be inspected and in the direction of the body axis to photograph the tomographjic image and whole-body image. At this time, the two detectors 19a and 19b which have the rectangular effective visual fields having the long sizes in the width direction of the top plate 24 are provided at the periphery of the center axis 16 opposite each other in a rotary ring 15 which is driven to rotate around the center axis 16 of rotation of the stand 10. By the whole-body image photography, the front and back can be photographed at the same time and by the tomography, an indicated position of the body to be inspected can be photographed by 180 deg. rotation. Therefore, the photography times of them can drastically be shortened.
