X-ray diagnostics installation having an image intensifier video chain

摘要

An x-ray diagnostics installation having an image intensifier video chain which back-projects a region of primary medical interest within an x-ray image into the overall video image is provided with fiber optics and opto-electronic transducers which are actuated by a switching bank in accordance with the desired shape and position of the region of primary interest. The transducers and switching arrangment can be removed, so that the output image from the x-ray image intensifier can be viewed at the output side of the fiber optics.
