In a nuclear imaging tomographic scanner, a drive mechanism is included to selectively move the patient in an axial plane to thereby maintain a close proximity to the detector for the purpose of increasing resolution. In this way, the actual movement of the camera head is in a simple circle whereas the relative movement of the camera head with respect to the patient is one wherein the detector tends to follow the general contour of the patient by the movement within an oval path.
