Abstract
A cassette for x-ray film has a cover and a bottom. A magnetic sheet is secured to the cover and a fluorescent screen is, in turn, secured to the magnetic sheet. A ferromagnetic foil is mounted on the bottom of the cassette and carries a second fluorescent screen. When a sheet of film is inserted in the cassette and the cassette is closed, the film is flanked by the fluorescent screens, which, in turn, are flanked by the magnetic sheet and the ferromagnetic foil. The magnetic sheet and ferromagentic foil are attracted to one another and thereby urge the fluorescent screens into engagement with the film. The ferromagnetic foil is mounted on the bottom of the cassette via connecting elements which permit the ferromagnetic foil to undergo relatively large amounts of movement relative to the bottom of the cassette. In this manner, the ferromagnetic foil can conform to deformation of the cassette. Each of the connecting elements includes a flexible strip which carries an adhesive layer at both of its longitudinal edges, and the adhesive layers are offset relative to one another. One of the adhesive layers is located on that surface of the flexible strip which faces the bottom of the cassette and engages only the flexible strip and the bottom of the cassette. The other adhesive layer is situated on that surface of the flexible strip which faces the ferromagnetic foil and engages only the flexible strip and the ferromagnetic foil.
