Abstract

The apparatus comprises an assembly consisting of an X-ray source and an X-ray detector. The assembly is moved incrementally about the subject in steps of 360/n degrees, n being odd. This ensures that, at every position Pn of the assembly at which absorption information is derived, the detector does not occupy any position previously occupied by the source. The assembly may be translated as well as rotated. The source may provide a fan beam. <IMAGE>
