Abstract

A process and device for producing a radiographic image of a body employ a source of high-energy radiation arranged on one side of the body and a pick-up device arranged on the other side of the body, a real-time system for reproducing the radiographic image having a television camera and a screen, and a computer-tomograph to evaluate the radiographic image row-wise and to display a cross-section of the radiographed body on the screen. By means of the real-time radiographic image a cross-section is selected and represented computer-tomographically. In this manner in the real-time radiographic image the location can be determined of which a layer image is necessary in order to recognise defects in the body being radiographed.
