Abstract
A flexible film cassette for holding a dental x-ray film on the outside of a patient's mouth for exposure from a radiation source from an x-ray diagnostic installation or device in which an applicator is capable of being inserted intraorally in the patient's mouth characterized by a first support extending between an applicator and the cassette and a second support spaced an interval from the axis of the first support for forming a coupling between the film and the housing of the x-ray device to prevent rotation of the cassette relative to the applicator.
