For many patients, stereotactic radiosurgery (SRS) offers a minimally invasive, curative option when surgical techniques are not possible. To date, the literature supporting the efficacy and safety of SRS treatment techniques uses photon beams. However, with the number of proton therapy facilities exponentially growing and the favorable physical properties of proton beam radiation therapy, there is an opportunity to develop proton therapy techniques for SRS. The goal of this paper is to determine the ability of clinical proton treatment planning systems to model small field dosimetry accurately and to compare various planning metrics used to evaluate photon SRS to determine the optimum beam configurations and settings for proton SRS (PSRS) treatment plans. Once established, these plan settings were used to perform a planning comparison on a variety of different SRS cases and compare SRS metrics between the PSRS plans and HyperArc™ (VMAT) SRS plans.

质子与Hyperarc™放射外科：计划比较

对于许多患者，立体定向放射外科手术（SRS）在无法使用外科手术技术时提供了微创的治疗选择。迄今为止，支持SRS治疗技术有效性和安全性的文献使用光子束。然而，随着质子治疗设施的数量成倍增加以及质子束放射治疗的良好物理特性，有机会对SRS开发质子治疗技术的机会。本文的目的是确定临床质子治疗计划系统准确建模小剂量学剂量的能力，并比较用于评估光子SRS的各种计划指标，以确定质子SRS（PSRS）治疗计划的最佳射束配置和设置。一旦建立，
