Halcyon直线加速器的出现增加了放射肿瘤学中常见治疗部位的患者吞吐量并缩短了治疗时间。然而,已经表明,与使用扁平辐射束的传统机器进行治疗相比,这可能导致乳腺癌等部位的表面剂量增加。切伦科夫成像可用于通过检测与来自组织中的高能电子的能量沉积成比例地发射的切伦科夫光子来估计表面剂量。在参考条件和临床治疗中使用两种方形射束进行体模研究,剂量计读数和切伦科夫图像报告Halcyon射束输送的表面剂量(平面体模入射剂量为25%,乳房体模治疗为5.9%)高于TrueBeam直线加速器的等效输送。此外,采集了接受Halcyon治疗的患者的第一个Cherenkov图像,并估计了浅表剂量。
The emergence of the Halcyon linear accelerator has allowed for increased patient throughput and improved treatment times for common treatment sites in radiation oncology. However, it has been shown that this can lead to increased surface dose in sites like breast cancer compared with treatments on conventional machines with flattened radiation beams. Cherenkov imaging can be used to estimate surface dose by detection of Cherenkov photons emitted in proportion to energy deposition from high energy electrons in tissue. Phantom studies were performed with both square beams in reference conditions and with clinical treatments, and dosimeter readings and Cherenkov images report higher surface dose (25% for flat phantom entrance dose, 5.9% for breast phantom treatment) from Halcyon beam deliveries than for equivalent deliveries from a TrueBeam linac. Additionally, the first Cherenkov images of a patient treated with Halcyon were acquired, and superficial dose was estimated.
