ABSTRACT:
A radiographic cassette comprises a bottom and a cover capable of being locked together. The cover has a part of its normally rigid structure replaced by a flexible foil which, when vacuum is aplied to the interior of the cassette, exerts a pressure upon the film/screen combination contained within the latter. In this way an intimate contact between the film and the screen is established and at the same time the distance between the film/screen combination and the object to be radiographed is reduced to a minimum due to the small thickness of the foil.
The cassette may be used in the field of high-definition radiography especially for mammography.
