Abstract
Portal radiographic imaging can be carried out using any suitable imaging equipment because of a modification to the imaging assembly to give it more flexibility for various imaging conditions. The imaging assembly includes a radiographic film, and at least one fluorescent intensifying screen. Disposed between the film and screen is a filter that attenuates the light emitted from the intensifying screen during exposure of the film.
