《GB/T 24791.3-2009摄影医疗X射线成像用屏/片系统的感光测定第3部分：乳腺X射线成像感光特性曲线形状、感光度与平均斜率的测定》由TC102（全国感光材料标准化技术委员会）归口，主管部门为中国石油和化学工业联合会。
GB/T24791的本部分描述了乳腺X 射线屏/片/片夹/加工系统的感光特性曲线形状、平均斜率与感光度的测定方法。片夹可以是任何形式,只要确保屏/片紧密接触,防止胶片被周围光线曝光即可。片夹可以是一种经常在实验中使用的不漏光的真空袋,或者在乳腺X 射线照相过程中使用的X 射线成像暗盒。

Scope

This part of GB/T 24791 describes the methods for measuring the shape, average slope and sensitivity of the sensitivity characteristic curve of mammography screen/film/film holder/processing system. The film holder can be in any form, as long as the screen/film is in close contact to prevent the film from being exposed to ambient light. The film holder can be a light-tight vacuum bag often used in experiments, or an X-ray imaging cassette used during mammography.
