ABSTRACT:
An x-ray film cassette includes two cassette parts which are connected at one side by a hinge and which are cylindrically curved as considered in a plane normal to the hinge. The cassette part which constitutes the bottom carries a foil of ferromagnetic material floatingly supported on an elastic strip-sloped peripheral frame, and an intensifying shield supported on this foil, while the other cassette part which constitutes the top carries a magnetic plate supported on elongated projections of the cassette wall and supporting another intensifying shield. In the closed position of the cassette, the magnetic plate attracts the ferromagnetic foil to thereby eliminate air inclusions between the intensifying shields and the x-ray film interposed therebetween.
