  • X-ray examination table with pivotally connected film holder
    Patent number: 5111496
    Abstract: A film holder is pivotably connected to a table frame of a patient table. By positioning the film holder so that an image plane thereof extends parallel to the table top, X-ray images can be recorded on film. In the folded-up condition, the image plane of the film holder extends parallel to the table frame so that the film holder does not form an obstruction for the formation of X-ray images by means of an X-ray image intensifier tube. The position of the film holder enables a fast change-over from exposures using an X-ray image intensifier tube to recording on film.
