标准范围

ISO 9236的本部分规定了测定感光曲线形状、平均梯度和温度的方法乳房X光摄影中屏幕/胶片/胶片夹/处理系统的单个样本的速度。胶片夹可以是确保屏幕/胶片紧密接触并防止胶片被损坏的任何方式暴露在环境光下。尤其是，胶片夹可以是一个不透光的真空袋，就像在电影中经常使用的那样实验室，或乳房X光摄影术中使用的射线照相盒。注:下文中，屏幕/胶片/胶片夹组合将被称为“组合”，并将被称为包括处理时的“系统”。

This part of ISO 9236 specifies methods for determination of the sensitometric curve shape, average gradient andspeed 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 beingexposed to ambient light. In particular, the filmholder may be a light-tight vacuum bag, as often used in thelaboratory, 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.
