BS ISO 9236-1-2004

摄影 医疗X射线照相用屏幕/胶片系统的感光学 第1部分:感光度曲线形状,速度和平均斜率的测定

Photography. Sensitometry of screen/film systems for medical radiography. Determination of sensitometric curve shape, speed and average gradient

适用范围:This part of ISO 9236 specifies methods for the determination of the sensitometric curve shape, average gradient and speed of a single sample of a screen/film/filmholder/processing system for medical radiography. It is not applicable to special radiographic applications such as mammography, dental radiography and direct-exposing medical radiographic systems (see for example ISO 5799 ). The filmholder can be any means that ensures close screen/film contact and prevents the film from being exposed to ambient light. In particular, the filmholder can be a light-tight vacuum bag, as often used in the laboratory, or a radiographic cassette as used in medical radiography.
