摘要

目的:准确了解皮肤辐照的表面剂量分布是皮肤辐照的关键问题。本研究采用Eclipse治疗计划系统(TPS)计算和GAF变色膜测量方法探讨表面剂量对乳腺癌治疗的影响。材料和方法:本研究采用非均匀胸模。用线性加速器(瓦里安2100C/D)的6 MV能量束辐照。比较TPS计算和膜测量的表面剂量估计。结果:薄膜测量值与TPS计算值的平均差异为7.1%。TPS计算中的表面剂量比薄膜测量中的低。结论:TPS在放疗中有重要作用。然而，它们在测量表面剂量时存在许多误差。由于大多数处理计划系统在计算表面剂量方面的不准确性，需要实际测量是必不可少的。

An Investigation into the Surface Dose Using Eclipse Treatment Planning System and Film Dosimetry for Treatment of Breast Cancer

Purpose: Accurate knowledge about surface dose distribution is a critical issue in skin irradiation. This study was conducted to investigate the surface dose using the Eclipse Treatment Planning System (TPS) calculation and GAF chromic film measurement for breast cancer treatment. Materials and Methods: An inhomogeneous chest phantom was used in the present study. Irradiations were done with a 6 MV energy beam of a linear accelerator (Varian 2100C/D). TPS calculations and film measurements were compared for surface dose estimations. Results: The average difference between film measurements and TPS calculations was 7.1%. Surface doses were lower in TPS calculations in comparison with film measurements. Conclusion: TPS plays a significant role in radiotherapy. However, they have many errors in measuring surface doses. Because of the inaccuracy of the majority of treatment planning systems in calculating the surface dose, the need for practical measurements is essential.
