Abstract
An improved x-ray film cassette including a film support plate and a resilient concave-convex window member formed of a highly x-ray transparent material. The convex side of the window member is positioned facing the film supporting plate so that when the cassette is loaded with film, the window member is deformed into a substantially flat shape and the film is clamped over its entire surface area between the window member and the support plate.
