This part of ISO9236 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.
