Abstract
An improved emission computerized tomography (ECT) drive mechanism for an Anger-type scintillation camera is disclosed. A support arm, carrying the camera head at one end and a counterweight at the other, is mounted on a universal joint and driven about the joint by a crank. The crank comprises an acme-type screw and the arm attaches to the crank at a point distant from the joint by means of an acme nut. The tilt angle of the arm is varied by varying the position of the acme nut on the acme screw.
