A film holder which is disclosed herein includes a inner frame defining a photo-sensitive plate insert slot between a partition plate, and outer frames each defining a dark slide insert groove between said inner frame. In this film holder, a plurality of stopper springs are formed on the peripheral sides of a body which is comprised of the partition plate and the inner frame. A plurality of hooks are formed on each the outer frames which are overlaid on the body to define the dark slide insert slot. These stopper springs and hooks are in the corresponding relationship, respectively, so that they are engaged with each other to lock the body and outer frames together in an overlaid relationship.
A corner element for an x-ray cassette for providing increased durability and light integrity. The x-ray cassette includes an upper and lower panel, a first member joining the upper and lower panels to define a cavity therebetween, and a storage phosphor assembly adapted to be removably contained within the cavity. The corner element comprises an upper and lower corner channel for receiving, respectively, the upper and lower panels; and a first leg adapted to mate with the first member and having an inclined element integrally formed therewith, the storage phosphor assembly being disposed adjacent to the inclined element when contained within the cavity.
A cassette for a photographic element of the kind used in computed radiography comprises a first cassette portion and a second cassette portion that are telescoped together during assembly to form the cassette. The first portion has a rectangular panel and edge walls extending around three side edges of the panel. The second cassette portion comprises a rectangular panel on which the photographic element is permanently secured. An edge wall is attached to one side edge only of the rectangular panel of the second cassette portion and it extends between the edge walls of the first cassette portion when the two portions are assembled together. A locking mechanism carried by the cassette portions holds them together in assembled relation but is easily released by an actuator for removing the second cassette portion and the photographic element so they can be delivered together to a computed radiography reader.
