Nettet6. nov. 2016 · 2.2.1 Screen Film (SF) Radiography. SF radiography uses intensifying screens and a radiographic film sandwiched in a light tight cassette (Fig. 4.11). A dark room and a wet chemical processor is required to develop the radiographs. Exposure of X-ray radiation produces an invisible latent image within the film emulsion. NettetIncreased film speed, when used with the same intensifying screens, results in an increase in quantum "noise." Nevertheless, this increased noise is not the primary degrading factor of diagnostic quality during arteriography and cross-table myelography. The authors show that the use of high-speed fi …
