In this work a spreadsheet based program is presented that to a large extent independently verifies the calculations of individual plans of brachytherapy treatment planning systems for low dose rate, high dose rate and pulsed dose rate techniques.
The verification program has been developed based on workbooks/spreadsheets. The treatment planning system output text files are automatically loaded into the new program, allowing the use of the source coordinates, the desired calculation point coordinates, and the dwell times of a patient plan. The source strength and the reference dates are entered by the user and then dose points calculations are independently performed. The program shows its results in a comparison of its calculated point dose data with the corresponding TPS outcome.
Results of 250 clinical cases show agreement with the TPS outcome within a 2% level.
The program allows the implementation of the recommendations to verify the clinical brachytherapy dosimetry in a simple and accurate way, in only few minutes and with a minimum of user interactions.
在本研究中，展示了一个基于电子表格的程序，该程序在很大程度上能独立验证近距离放射治疗计划系统针对低剂量率、高剂量率和脉冲剂量率技术的个体计划计算。
验证程序是基于工作簿/电子表格开发的。治疗计划系统输出的文本文件会自动加载到新程序中，从而可以使用患者计划的源坐标、所需计算点坐标和驻留时间。源强度和参考日期由用户输入，然后独立进行剂量点计算。该程序通过将其计算的点剂量数据与相应的治疗计划系统结果进行比较来展示结果。
250例临床病例的结果显示与治疗计划系统结果在2%的水平内相符。
该程序能够以简单、准确的方式实施相关建议，仅需几分钟且用户交互最少即可验证临床近距离放射治疗剂量学。
