ABSTRACT:
An emission type computed tomography apparatus comprises a mechanism for rotating a detector along a circle centered at a human body to whom radioisotope is previously given, and a circuit for reconstructing a tomogram in accordance with an output signal from said detector. The rotating mechanism further has a member for slanting the detector with respect to a tangential line of the circle, a member for slanting said detector with respect to the body axis, and a member for changing the radius of the rotating circle of the detector.
