ICRP第145号出版物成人网格参考计算体模 （Adult Mesh-type Reference Computational Phantom）
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...
