Abstract

Our institutional approach to performing periodic constancy checks on dose calculations for the Varian Eclipse treatment planning system is described, including details of how the Radformation ClearCheck software is leveraged for highly efficient results analysis. Photon- and electron-specific synthetic phantoms are created which allow all modality-specific fields to be spatially separated and calculated in a single plan, with field-specific structures encompassing individual irradiated volumes facilitating field-specific dose distribution evaluations. Plan comparison templates in ClearCheck allow for the near-instantaneous evaluation of 116 and 165 individual calculation metrics for photon and electron fields, respectively. The methodology is further applied to the Radformation ClearCalc finite-size pencil beam and electron algorithms for secondary algorithm validation. The total time required for constancy evaluations of 6 primary algorithms and 4 secondary algorithms is less than one hour, with much of that time used for passive dose calculation.

技术报告：在第三方ClearCheck软件的帮助下，对Eclipse治疗计划系统的光子和电子剂量计算算法进行有效的恒定性评估。

描述了我们对Varian Eclipse治疗计划系统的剂量计算进行定期恒定性检查的机构方法，包括如何利用Radformation ClearCheck软件进行高效结果分析的细节。创建了光子和电子特异性合成模型，允许在单个计划中对所有模态特异性场进行空间分离和计算，场特异性结构包括单个照射体积，有助于场特异性剂量分布评估。ClearCheck中的计划比较模板允许分别对光子场和电子场的116和165个单独计算度量进行近乎即时的评估。该方法进一步应用于Radformation ClearCalc有限尺寸铅笔束和电子算法，用于二次算法验证。6种主要算法和4种次要算法的恒定性评估所需的总时间不到一小时，其中大部分时间用于被动剂量计算。

期刊介绍： Medical Dosimetry, the official journal of the American Association of Medical Dosimetrists, is the key source of information on new developments for the medical dosimetrist. Practical and comprehensive in coverage, the journal features original contributions and review articles by medical dosimetrists, oncologists, physicists, and radiation therapy technologists on clinical applications and techniques of external beam, interstitial, intracavitary and intraluminal irradiation in cancer management. Articles dealing primarily with physics will be reviewed by a specially appointed team of experts in the field.
