PURPOSE:To eliminate positional shift and to obtain a continuous whole body image by detecting the positional shift quantity in a horizontal detection generated when an gamma camera is retracted and reopening the movement of the gamma camera corresponding to the positional shift quantity after retraction to correct the position of an image. CONSTITUTION:Rails 3 are laid on the floor surface on the side of the longitudinal direction of a bed 1 in parallel to the bed 1. A moving mechanism 4 is equipped with the wheels tumbling on the rails 3 and a frame 6 having a hole 5 formed to the central part thereof is provided to the upper part of the mechanism 4. Support arms 7 are provided in the hole 5 so as to pierce through the hole 5 and mounted on the support shafts 8, 9 provided to the inner peripheral wall part of the hole 5 in a shakable manner. A gamma camera 10 for detecting the radiation emitted to an examinee M is supported between the end parts on the side of the examinee M of the arms 7 and a counter wt. 11 is mounted on the end parts thereof on the opposite side. A touch sensor is mounted on the leading end part of the camera 10 in the moving direction thereof.
