We have applied digital fluoroscopy technology to the radiation therapy environment, and developed a real-time fluorescent dosemeter (RFD). Our aim was to utilise this system as an on-line treatment verification device. We have found that the system behaves basically as a large array (512 X 512) of dosemeters. Using this device, instantaneous information about the actual treatment beam can be obtained simultaneously with the commencement of irradiation. As an array of dosemeters, it provides a detailed description of the dose distribution (exit dose) throughout the treatment. Furthermore, by applying image enhancement techniques to this measured information, good quality portal images are produced instantaneously and continuously during the entire irradiation for visual evaluation. The availability of this system should lead to improvements in precision in present dose delivery procedures.
我们已将数字荧光透视技术应用于放射治疗环境，并开发了一种实时荧光剂量计（RFD）。我们的目标是将该系统用作在线治疗验证设备。我们发现该系统基本上表现为一个剂量计的大型阵列（512×512）。使用该设备，可以在照射开始时同时获得有关实际治疗束的即时信息。作为剂量计阵列，它提供了整个治疗过程中剂量分布（出射剂量）的详细描述。此外，通过对这些测量信息应用图像增强技术，可以在整个照射过程中即时且连续地生成高质量的射野图像以供视觉评估。该系统的可用性应会提高当前剂量输送程序的精度。
