PHD. 77-023 8.3.78 ABSTRACT: The invention enables the density distribution in a plane, in particular in a planar slice of a body, to be reproduced with the aid of scattered radiation. A narrow X-ray beam is then passed through the body to be examined. The scattered radiation produced in the path of said primary beam through the body reaches an array of detectors through a slot diaphragm which is disposed outside the primary beam, the slot diaphragm and the detectors being arranged so that each detector can only measure a spatially limited part of the scattered radiation originating from the primary beam. Thus, at the end of a measurement the detector output signals represent a qualitative image of the density distribution inthe body along the primary beam. Subsequently, the body is moved by approximately the width of the primary beam normal to the direction of said beam, thus enabling line scanning to be realised.
