Type I型光敏剂因其对氧气比较低的依赖性，可以解决Type II 型光敏剂因实体肿瘤乏氧带来的预后不良的问题，逐渐成为光动力治疗领域的研究热点。Type I 型光动力治疗机制的核心是光敏剂的电子转移能力。这个能力包括两个方面，一方面是光敏剂从底物中获得电子，另一方面是光敏剂要将捕获的电子提供给O2，从而形成活性氧超氧阴离子自由基（O2226;W22;）。然而，大多数现有的光敏剂只能...

成人网格 参考计算体模 ICRP 第145号出版物 剂量系数计算
2023/3/9
继2007年建议(第103号出版物)之后，ICRP在第110号出版物(2009年)和第143号出版物(2020年)中发布了用于剂量系数计算的体素参考计算体模(VRCPs)系列。 基于真人CT图像的VRCPs改进了解剖学和剂量学，而不是在2007年建议之前用于剂量系数计算的老式数学(或风式化)体模。然而，这种由体素大小固定的体素组成的体素体模在表示某些解剖结构，特别是那些比体素尺寸更小或更薄的体素体...
