ABSTRACT:
A substrate transparent to x-rays mounts a resilient layer transparent to x-rays, and an overlying thin blocker layer of fracturable lead or tin foil which is opaque to x-rays. When impressed or typewritten the blocker layer is selectively stenciled or fractured to permit selective passage of x-rays therethrough. The substrate or a perforated portion thereof mounting the stencil, is emplaced upon an x-ray cassette during x-ray exposure to capture the stencilized data in the permanent film image. Visual inspection of stencilized data may be aided by a white paint layer disposed upon the blocker layer. Affixation to the film or cassette may be aided by a pressure sensitive adhesive layer in an area adjacent the other superimposed layers.
