In previous work, we demonstrated that mixed electron-photon radiation therapy (MBRT) produces treatment plans with improved normal tissue sparing and similar target coverage, when compared to photon-only plans. The purpose of this work was to validate the MBRT delivery process on a Varian TrueBeam accelerator and laying the groundwork for a patient-specific quality assurance (QA) protocol based on ion chamber point measurements and 2D film measurements.

基于离子室和薄膜的混合电子光子放射治疗质量保证

在之前的工作中，我们证明了与仅光子计划相比，混合电子光子放射治疗 (MBRT) 产生的治疗计划具有更好的正常组织保留和相似的目标覆盖范围。这项工作的目的是验证 Varian TrueBeam 加速器上的 MBRT 传输过程，并为基于离子室点测量和 2D 薄膜测量的患者特定质量保证 (QA) 协议奠定基础。
