BS ISO 9236-3:1999

Photography. Sensitometry of screen/film systems for medical radiography. Determination of sensitometric curve shape, speed and average gradient for mammography | Status: Confirmed, Current

1 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 cassette as used in mammography.

NOTE — Hereafter, screen/film/filmholder combinations will be referred to as "combinations", and will be referred to as "systems" when the processing is included.
