X-ray diagnostic apparatus with an image intensifier television system and indirect camera

摘要

The invention relates to an X-ray diagnostic apparatus with an image intensifier television system (5 to 8) and an indirect camera (6a). An iris aperture (11) is fitted on the housing of the X-ray image intensifier (5), in front of its input fluorescent screen (10), by means of which aperture (11) the area of the input fluorescent screen (10) which is subjected to radiation can be adjusted. In this way, it is possible to reduce the effect of scattered radiation, which detracts from the X-ray image. IMAGE
