Apparatus for capturing two-dimensional images created by radioactive emanations, such as gamma rays, from a radioactive source, comprises a collimator, a two-dimensional array of scintillating fibers, and position encoding apparatus. The scintillating fibers are located at preselected x and y positions in an x-y plane. The position encoding apparatus comprises banks of photon detectors and a network of optical fibers which are connected to the photon detectors in a manner which encodes the x-y coordinates of the scintillating fibers, and a signal processor for generating position signals indicative of the encoded position of an active scintillating fiber.
