Film-based cassettes are the ones that contain radiographic film and directly receive the x-ray beam. When the film is exposed, it records a latent image that must be chemically developed to produce the visible radiograph. This contrasts with imaging plate systems, which use a photostimulable phosphor plate inside the cassette and require a scanner to read out the digital image, and with digital detectors that convert x-rays directly to electronic signals. The term radiograph refers to the final image, not the cassette itself. So the cassette containing film is the film-based type.
