The surface-guided radiotherapy (SGRT) technique improves patient positioning with submillimeter accuracy compared with the conventional positioning technique of lasers using three-point tattoos. SGRT provides solutions to considerations that arise from the conventional setup technique, such as variability in tattoo position and the psychological impact of the tattoos. Moreover, SGRT provides monitoring of intrafractional motion.
This literature review covers the basics of SGRT systems and examines whether SGRT can replace the traditional positioning technique. In addition, it investigates SGRT's potential in reducing positioning times, factors affecting SGRT accuracy, the effectiveness of live monitoring, and the impact on patient dosage.
This study focused on papers published from 2016 onward that compared SGRT with the traditional positioning technique and investigated factors affecting SGRT accuracy and effectiveness.
RESULTS/CONCLUSIONS: SGRT provides the same or better results regarding patient positioning. The implementation of SGRT can reduce overall treatment time. It is an effective technique for detecting intrafraction patient motion, improving treatment accuracy and precision, and creating a safe and comfortable environment for the patient during treatment.
与使用三点纹身的传统激光定位技术相比，表面引导放疗（SGRT）技术能将患者定位精度提高到亚毫米级。SGRT解决了传统设置技术中出现的一些问题，比如纹身位置的变异性以及纹身带来的心理影响。此外，SGRT还能监测分次治疗期间的运动。
这篇文献综述涵盖了SGRT系统的基础知识，并探讨了SGRT是否能取代传统定位技术。此外，还研究了SGRT在缩短定位时间方面的潜力、影响SGRT精度的因素、实时监测的有效性以及对患者剂量的影响。
本研究聚焦于2016年及以后发表的将SGRT与传统定位技术进行比较，并研究影响SGRT精度和有效性因素的论文。
结果/结论：在患者定位方面，SGRT能提供相同或更好的结果。SGRT的实施可以缩短总体治疗时间。它是一种检测分次治疗期间患者运动、提高治疗准确性和精确性以及在治疗期间为患者创造安全舒适环境的有效技术。
