伊斯曼-柯达公司于1981年后期供应一种齿部摄影用的胶片,这种胶片可以使病人和操作者受到的X射线剂量降低50％,比柯达超速齿片的速度快一倍。胶片与长锥体射线摄影技术和为短时间曝光设计的X射线发生装置一起配合使用。
In 1981, Eastman Kodak supplied a film for photographic imaging that reduced the dose of X-rays received by patients and operators by 50%, and was twice as fast as the Kodak ultra-speed blade. Film and long cone radiography techniques are used in conjunction with X-ray generators designed for short exposures.
