Usually made on the x-ray by photographic means or by using radiopaque tape. film marker any device, usually lead letters, placed on the film to indicate which part of the animal was examined and the projection used. nonscreen film film for getting very fine detail, used without a cassette and requiring long exposure time. This film is now banned in some parts of the world. plain film an x-ray film taken without contrast medium or other special effects. Often an exploratory or scout film. spot film a radiograph of a small anatomic area obtained (1) by rapid exposure during fluoroscopy to provide a permanent record of a transiently observed abnormality, or (2) by limitation of radiation passing through the area to improve definition and detail of the image produced. standard film fine-grain, medium-speed with wide tolerance for exposure times. x-ray film film sensitized to x-rays, either before or after exposure.
