Abstract
A system of radiography includes the provision of a cassette which is to be subjected to exposure from radiation beam. The cassette includes a screen layer and a filter layer having regions of different optical density and an imaging film. The filter acts to reduce the exposure of the film to the effect of radiation. The cassette is useful for dental images, particularly of the temporamandibular joint.
