ABSTRACT:
A medical diagnostic X-ray machine is described in which X-ray measurements are taken of the attenuation suffered by X-radiation when projected across a cross-sectional slice of a patient's body along each of many substantially linear beam paths and are subjected to compensated back-projective processing to produce an X-ray picture representing the variation of attenuation of the radiation with position over the slice. Neighboring beam paths are arranged to overlap each other.
