Description
By representing an image as a distribution of Gaussian blobs, due account is taken, for a single photon emission computed tomography (SPECT) system, of finite detector resolution (leading to spatially varying image resolution) and constant attenuation of the radiations on their passage through a body. A simple enhancement procedure is proposed. It is argued that the effects of variable attenuation (as must occur in practice) are unlikely to be important in general. (author)
