Abstract

The x-ray machine, can illuminate a body selectively in one dimension or in two dimensions. It consists of an x-ray source, a screen and an opto-electrical image processing circuit. It has an anamorphotic optical system (5), which is placed between the x-ray screen (3) and the optical-electrical devices, when using one dimensional illumination. It is removed for two dimensional illumination. There is an apparent magnified image looked at from the lens system (4), when the distance between the screen and the lens system remains constant.
