Abstract
Abstract Apparatus for producing a shadow image of an object (12) by means of X-rays comprises a housing (1) which accommodates an X-ray source (2) directed onto a fluorescent screen. Located between the screen and the radiation source is an object station (15). In accordance with the invention there is located between the object station (15) and the screen (4) an X-ray permeable mirror (16) which is positioned obliquely in relation to the radiation path (3) and which is adapted to project a section of the screen onto a television camera (17) which is arranged on one side of the radiation path (3) and which is connected to a television monitor (36) in order to show this section of the screen.
