Abstract：
UNASSIGNED: To evaluate the use of this new technique, surface-guided radiotherapy (SGRT), for patient setup and motion management in various cancers.
UNASSIGNED: Data was collected from 533 patients, who received treatment in our hospital for various malignancies using SGRT from October 2019 to April 2021. We studied patient setup, interfraction position, and patient position during the breath-hold (BH) technique. The main advantage of SGRT is that, it is completely non-invasive and uses visible light to compare the patient\'s skin surface in the treatment room and planned treatment position. In this analysis, Monaco 5.51.10 (Elekta) treatment planning system, Versa HD Linear Accelerator, and AlignRT 6.2 (Vision RT) SGRT system were used.
UNASSIGNED: With SGRT, treatment setup time can be reduced with more precision and techniques like Deep inspiration breathhold (DIBH) can be done with very good compliance.
UNASSIGNED: SGRT has shown improved accuracy in patient setup compared to conventional laser setup. The daily kilo voltage imaging frequency can be reduced; it helps in reducing additional radiation exposure due to imaging. SGRT has demonstrated reproducibility with adequate accuracy in BH treatments in DIBH for breast and SBRT.

摘要：
■为了评估这项新技术的使用，表面引导放射治疗（SGRT），用于各种癌症的患者设置和运动管理。
■数据来自533名患者，从2019年10月至2021年4月，他在我们医院接受了使用SGRT治疗各种恶性肿瘤的治疗。我们研究了病人的设置，分数位置，以及屏气（BH）技术期间的患者位置。SGRT的主要优点是,它是完全非侵入性的，并使用可见光来比较患者在治疗室和计划治疗位置的皮肤表面。在这个分析中,摩纳哥5.51.10（Elekta）治疗计划系统，VersaHD线性加速器,使用AlignRT6.2(VisionRT)SGRT系统。
■使用SGRT，治疗设置时间可以减少与更高的精度和技术，如深吸气呼吸（DIBH）可以做很好的依从性。
■与常规激光设置相比，SGRT在患者设置中显示出提高的准确性。可以降低每日千伏电压成像频率;它有助于减少由于成像引起的额外辐射暴露。SGRT已证明在DIBH治疗乳腺和SBRT的BH治疗中具有足够的可重复性。
