摘要
目的利用Solaris 10操作系统中自带的Perl程序创建具有自适应性质的动态脚本,实现调强放射治疗(IMRT)计划设计的自动执行,并研究其在计划设计中的应用前景。方法选取6例食管癌患者,利用Perl程序创建动态脚本,通过脚本回放,实现IMRT放疗计划的设计,并利用体积剂量,计划完成时间等参数与人工设计的计划进行对比。结果在不明显改变计划质量的前提下,脚本计划时间(12.70±1.47)min相比人工计划时间(27.72±2.29)min平均缩短15 min,差异有统计学意义(P<0.05)。结论利用Perl程序创建动态脚本能够自适应靶区与剂量,通过脚本回放可快速完成IMRT计划的设计。
Objective Underwent adaptive dynamic scripts based on the Perl program of Solaris 10 operating sys-tem and scripting playback of pinnacle system which automatically performed the plan of intensity modulated radio-therapy and analyzed the dose distribution produced by the dynamic scripts, and then explored them in the treat-ment plan of intensity modulated radiotherapy. Methods Six patients with esophageal carcinoma received radiother-apy were selected. Two IMRT plans for each patient were designed： the artificial plan and the plan based on the dynamic scripts through playback function. The dose volume histogram, plan completion time, and other parame-ters were compared respectively. Results The average time of IMRT plan（12. 70 ± 1. 47） minutes achieved by the application of dynamic scripts was 15 minutes shorter than that of the artificial plan（27. 72 ± 2. 29） minutes, and the difference was statistically significant （ P〈0. 05 ） . Conclusion The dynamic scripts based on the Perl program can adapt the targets and dose, and can quickly fulfill the IMRT plan through playback function.
