ABSTRACT:
A x-ray fill cassette for use with radiographic film. The cassette has a tube side unit and a cover unit. The units together define a film space for the film. The units are relatively pivotable between an open state and a closed state. The tube side unit is substantially convex in at least one of length and width dimensions when the traits are in the open state. The tube side unit is substantially flat in both length and width dimensions when the film is in the film space and the units are in the closed state. The tube side unit includes a compressible pad that adjoins the fill space. The cover unit includes a cover panel, a pressure panel, and an intensifying screen. The cover panel and the pressure panel are rigidly mounted in spaced parallel relation. The intensifying screen is adhered directly to the pressure panel adjoining the film space. The convexity of the tube side unit and the compressible pad are selected to impose on the film, when the film is in the closed state, a substantially uniform compressive force of from about 0.09 psi to about 0.35 psi.
