QA OF TREATMENT DELIVERY BY MEANS OF OVERLAYED DIGITIZED STIMULATOR AND PORTFILMS

放射治疗一致性的质量保证 在当地，用处方分娩是一个持续的问题， 以及国家。 ROB已经采用了网格投影 所有模拟器胶片和所有相应的端口胶片上。 现在 项目正在启动，以覆盖不同的处理数字化 电影，以提高信息的质量，以及 减少需要保留的文件数量。 该系统应引起机构间 学习也是。 这个项目一直被搁置到最近 这是因为在购置基本硬件方面出现延误。 是 现在进展很快。

The quality assurance of the consistency of radiation treatment delivery with the prescription is a continual concern, locally as well as nationally. The ROB already employs graticules projecting onto all simulator films and all corresponding portfilms. Now a project is being started to overlay differently processed digitized films to increase the quality of information, as well as to decrease the volume of documentation to be retained. The system should be of great interest to inter-institutional studies as well. The project has been on hold until recently because of delays in acquisition of essential hardware. It is progressing rapidly now.
