With the advent of new complex but precise radiotherapy techniques, the demands for an accurate, feasible three-dimensional (3D) dosimetry system have been increased. A 3D dosimeter system generally should not only have accurate and precise results but should also feasible, inexpensive, and time consuming. Recently, one of the new candidates for 3D dosimetry is optical computed tomography (CT) with a radiochromic dosimeter such as PRESAGE®. Several generations of optical CT have been developed since the 90s. At the same time, a large attempt has been also done to introduce the robust dosimeters that compatible with optical CT scanners. In 2004, PRESAGE® dosimeter as a new radiochromic solid plastic dosimeters was introduced. In this decade, a large number of efforts have been carried out to enhance optical scanning methods. This article attempts to review and reflect on the results of these investigations.
随着新的复杂但精确的放射治疗技术的出现，对准确、可行的三维（3D）剂量测定系统的需求不断增加。一个3D剂量计系统通常不仅应具有准确和精确的结果，还应可行、廉价且耗时少。最近，3D剂量测定的新候选方法之一是使用如PRESAGE®等放射变色剂量计的光学计算机断层扫描（CT）。自90年代以来，已经开发了几代光学CT。与此同时，人们也进行了大量尝试，以引入与光学CT扫描仪兼容的坚固剂量计。2004年，PRESAGE®剂量计作为一种新型放射变色固体塑料剂量计被引入。在这十年中，人们为改进光学扫描方法付出了大量努力。本文试图回顾和反思这些研究的结果。
