通过应用简单，廉价，对比度增强技术的高能定位和验证膜的对比度，在高能定位和验证膜的对比度上进行了改善。该方法涉及将原始胶片的逆转接触“打印”到普通的X射线FI-M上，并使用任何放射治疗部门使用的设备。这导致“伽马乘法”。提出了这种效果的理论以及几种应用。
An order-of-magnitude improvment in the contrast of high-energy localization and verification films has been achieved through the application of a simple, inexpensive, contrast enhancement technique. The method involves making reversal contact "prints" of the original film onto ordinary X-ray fi-m with equipment commonly available in any radiotherapy department. This results in "gamma multiplication". The theory as well as several applications of this effect are presented.
