Abstract
The specification describes an information-bearing sheet suitable for use with an X-ray film. The sheet is formed of a mark-bearing portion, which is to be applied to the X-ray film and exposed to X-ray upon taking an X-ray picture of an object, and a data-filling portion bearing, in a form printed thereon, the same mark as the mark-bearing portion, containing at least one blank space adapted to fill identification data of the object and provided in combination with the mark-bearing portion. The mark may be printed with a lead-containing ink on the mark-bearing portion. When the X-ray film is exposed to X-ray with the mark-bearing portion applied thereon, the mark is automatically imprinted on the X-ray film. When taking the X-ray picture, the data-filling portion is filled with appropriate data on the object and is applied to a bag for storing or filing the X-ray picture. In this manner, the X-ray picture can be easily matched with its corresponding object without failure.
