Photography. Sensitometry of screen/film systems for medical radiography - Determination of sensitometric curve shape, speed and average gradient for mammography Ingestion-build-264231 Why should you use BS1 Scope This part of ISO 9236 specifies methods for determination of the sensitometric curve shape, average gradient and speed of a single sample of a screen film filmholder processing system in mammography. The filmholder may be any means which ensures close screen film contact and prevents the film from being exposed to ambient light. In particular, the filmholder may be a light tight vacuum bag, as often used in the laboratory, or a radiographic
