Abstract

There is disclosed an assembly for slit radiography with image equalization, comprising an X-ray source which can scan a body for examination via a slit of a slit diaphragm with a flat, fan-shaped X-ray beam over a scanning path in a direction transverse to the lengthwise direction of the slit for forming an X-ray shadowgraph on an X-ray detector; an absorption device which under the control of control signals can influence the fan-shaped X-ray beam per sector thereof, in order to permit control of the X-ray radiation falling in each sector on the body to be examined; and detection assembly which is designed to detect the quantity of X-ray radiation transmitted by the body instantaneously per sector during a scanning movement of the X-ray beam and to convert it into corresponding signals.
