Abstract

Radiological apparatus is described for producing a representation of the variation of absorption coefficient with position over at least one planar slice taken cross-sectionally through a body under examination. The source of radiation comprises an X-ray tube having a target with an extended dimension in a direction substantially perpendicular to the plane of the aforementioned planar slice, and means is provided for scanning the electron beam of the tube along the extended dimension of the target so as to scan the X-radiation relative to the body in said direction.
