ISO 9236-3:1999

Photography — Sensitometry of screen/film systems for medical radiography — Part 3: Determination of sensitometric curve shape, speed and average gradient for mammography

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.
