Abstract

Surface-guided radiotherapy (SGRT) has been increasingly implemented in modern radiation therapy practice. It can be utilized for patient positioning and real-time monitoring of organ motion during treatment. Furthermore, the system enables automatic beam interruption when the motion of the target or organ of interest deviates from the planned treatment position. Therefore, quality assurance (QA) of SGRT systems is essential to ensure treatment accuracy and patient safety. SGRT QA can generally be categorized into three levels: daily, monthly, and annual procedures. This article presents our institutional experience in the clinical application of SGRT for patient setup in radiation therapy, as well as the implementation of quality assurance procedures for the SGRT system. The aim is to provide practical guidance for the implementation and further development of SGRT in radiotherapy practice.
