标准摘要
[中文适用范围]： 本国际标准建立了测量用于存储医疗记录的照相胶片稳定性的测试方法。 它适用于基于热处理材料（光热成像、热成像、微胶囊）或通过喷墨打印创建的传输模式胶片上的灰度图像。 热处理材料以安全聚酯[聚对苯二甲酸乙二醇酯]为基础，主要与分散在非凝胶乳液或基于染料的微胶囊乳液中的山嵛酸银盐一起使用，经过热处理可产生黑白图像。 在喷墨印刷中，墨滴被喷射到具有墨接收层的薄膜上以产生灰度图像。 [外文原描述]： ISO 18939:2013 establishes test methods for measuring the stability of photographic films intended for storage of medical records. It is applicable to greyscale images on films for use in transmission mode that are based on thermally processed materials (photothermography, thermography, microcapsule) or created by inkjet printing. Thermally processed materials have a base of safety polyester [poly (ethylene terephthalate)] and work predominantly with silver behenate salts dispersed in non-gelatinous emulsions or dye-based microcapsule emulsions that are thermally processed to produce a black-and-white image. In inkjet printing ink droplets are jetted onto a film with an ink-receiving layer to produce a greyscale image. ISO 18939:2013 does not cover wet-processed black-and-white films or black-and-white paper. It is not applicable to medical colour images or colour prints created by colour inkjet or dye diffusion thermal transfer (D2T2). Neither does it cover medical greyscale images printed on reflective materials for referral purposes or filmless systems such as picture archiving and communication systems (PACS) in medical imaging. ISO 18939:2013 requires the arbitrary choice of "illustrative end points" for changes in colour and perceived contrast to depict quantifiable changes due to physical ageing. Extrapolations based on ?illustrative end points' do not have any proven diagnostic or clinical relevance due to the lack of corresponding statistically significant scoring by radiologists.
