Abstract
An image acquisition and reconstruction process for increasing the definition of the radiological image obtained by tomodensitometry. The invention consists in taking two series of data or 'views' and in arranging this data by causing the views W.sub.i of the second series to undergo a translation of --.pi..theta. and a symmetry --.gamma., in the space [.theta.,.gamma.], .theta. being equal to .beta.+.gamma.; .gamma. designates the angle between the different detectors and the straightline joining the origin of the fan-shaped X ray beam to the center of rotation of the source-detectors assembly and .beta. represents the different angles of the source-detectors assembly at which acquisition of the views is made.
