Abstract
Distortion is intrinsic to converging collimator scintiphotography although converging collimation offers improved resolution and sensitivity. The nature of the distortion is defined and compared to nondistorted parallel-hole collimator images. The analogy between long and short focal-film-distance radiographs, and parallel and converging hole collimators, is discussed.
