Resumen
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.
