Monte Carlo calculations of absolute dose rate in liquid water are presented in the form of away-along tables for 1 and 5 cm 192Ir wires of 0.3 mm diameter. Simulated absolute dose rate values can be used as benchmark data to verify the calculation results of treatment planning systems or directly as input data for treatment planning. Best fit value of attenuation coefficient suitable for use in Sievert-integrals-type calculations has been derived based on Monte Carlo calculation results. For the treatment planning systems that are based on TG43 formalism we have also calculated the required dosimetry parameters.
给出了液态水中绝对剂量率的蒙特卡罗计算结果，以沿轴向表格的形式呈现了直径为0.3 mm的1 cm和5 cm 192Ir丝的情况。模拟的绝对剂量率值可用作基准数据，以验证治疗计划系统的计算结果，或直接用作治疗计划的输入数据。基于蒙特卡罗计算结果，得出了适用于西弗积分型计算的衰减系数最佳拟合值。对于基于TG43形式主义的治疗计划系统，我们还计算了所需的剂量学参数。
