Effect of vertical cassette holder design and construction on scatter-to-primary radiation ratios.

Published

Journal Article

This paper analyzes the contribution to scattered radiation at the film plane by individual components of a conventional wall-mounted cassette holder. With grid technique, scatter from the front panel of the cassette holder is effectively reduced, but considerable scatter reaches the film plane from the automatic exposure control pickup interposed between the grid and the film cassette. With air-gap technique (grid removed), the front panel of the cassette holder and the automatic exposure control pickup contribute equally to increased scattered radiation at the film plane. The contribution to the total scatter from the air-gap positioning plate is less significant.
