cassette

1. a light-proof housing for x-ray film, containing front and back intensifying screens, between which the film is placed and held during exposure. Although it is usual to have two screens, there may be only one where there is a special need for a high detail picture.
2. a magazine for film or magnetic tape.

cassette grid
composed of alternating strips of lead and radiotranslucent material such as aluminum. Placed on top of the cassette it permits the passage only of the x-rays that are passing directly to the film. Scattered rays are absorbed by the lead and this reduces the effect of scatter on the film and provides a more clearcut image.
cassette holder
a radiolucent holder, into which the cassette fits, is on a long handle permitting the person holding the cassette to stay well clear of the x-ray beam.
cassette tunnel
a device which enables the operator to pass a number of cassettes past the x-ray beam and the grid without the need to open and reload cassettes.
