Abstract: An X-ray fluoroscopy device comprises a television camera for locating the irradiation field. This camera forms an optical image of the object to be irradiated. This image can be displayed on a television monitor, together with an image of the irradiation field, so that the position of the irradiation field within the object can be directly observed.
Abstract: Apparatus for examining objects includes a group of X-ray sources, which are activated group-wise by a generator. A group of sub-images are separately projected onto a photographic film. During a subsequent step, the film is re-imaged with the aid of an optical lens matrix the lenses in the matrix are arranged in a manner similar to the X-ray sources.
