Rotation of a system consisting of a single x‐ray source and a linear detector array allows rapid collection of x‐ray projection data from which transaxial cross sections can be reconstructed. In this paper, we present an algorithm which makes possible rapid computerized reconstruction from such data. We describe some experiments aimed at investigating the optimal choice of some of the parameters associated with the algorithm. We report on reconstructions using our algorithm of the intact thorax of a dog and also of cross sections of the human female breast from x‐ray data obtained by a computerized mammography machine.
