To update the Carleton Laboratory for Radiotherapy Physics (CLRP) TG‐43 dosimetry database for low‐energy (≤50 keV) photon‐emitting low‐dose rate (LDR) brachytherapy sources utilizing the open‐source EGSnrc application egs_brachy rather than the BrachyDose application used previously for 27 LDR sources in the 2008 CLRP version (CLRPv1). CLRPv2 covers 40 sources ( urn:x-wiley:00942405:media:mp14249:mp14249-math-0001Pd, urn:x-wiley:00942405:media:mp14249:mp14249-math-0002I, and urn:x-wiley:00942405:media:mp14249:mp14249-math-0003Cs). A comprehensive set of TG‐43 parameters is calculated, including dose‐rate constants, radial dose functions with functional fitting parameters, 1D and 2D anisotropy functions, along‐away dose‐rate tables, Primary‐Scatter separation dose tables (for some sources), and mean photon energies at the surface of the sources. The database also documents the source models which will become part of the egs_brachy distribution.

更新用于低能量近距离放射治疗源的 CLRP TG-43 参数数据库。

使用开源 EGSnrc 应用程序egs_brachy而不是BrachyDose应用程序更新卡尔顿放射治疗物理实验室 (CLRP) TG-43 剂量学数据库,用于低能量 (≤50 keV) 光子发射低剂量率 (LDR) 近距离放射治疗源以前用于 2008 CLRP 版本 (CLRPv1) 中的 27 个 LDR 源。CLRPv2 涵盖 40 个来源(骨灰盒:x-wiley:00942405:媒体:mp14249:mp14249-math-0001Pd、骨灰盒:x-wiley:00942405:媒体:mp14249:mp14249-math-0002I 和骨灰盒:x-wiley:00942405:媒体:mp14249:mp14249-math-0003CS)。计算了一组全面的 TG-43 参数,包括剂量率常数、具有功能拟合参数的径向剂量函数、1D 和 2D 各向异性函数、沿途剂量率表、初级散射分离剂量表(对于某些来源) ,以及光源表面的平均光子能量。该数据库还记录了将成为egs_brachy发行版一部分的源模型。
