概要	The purpose of this study was to evaluate the diffusion of surface-guided radiation therapy (SGRT), implementation of quality control and quality assurance strategies, established clinical workflows and user perceptions regarding the benefits and limitations of SGRT in routine practice. From October to December 2024, we surveyed 880 radiotherapy institutions in Japan regarding institutional characteristics, quality assurance/quality control, computed tomography simulation, treatment procedures and general questions regarding SGRT. The survey was distributed via mailing list and through vendors, and administered via Google Forms. A total of 292 institutions responded, corresponding to a response rate of 33%. Ninety-eight institutions reported introducing SGRT, and 50 institutions had introduced it after 2022. The highest usage rate of SGRT in breast treatment was 87%. Approximately half of the institutions performed daily checks of SGRT and radiation isocenter coincidence, as well as static accuracy, whereas 6% did not perform these checks at all. The primary functions of the SGRT system were patient positioning (94%), respiratory management (78%), patient monitoring (76%) and skin marker-less techniques (69%). Many institutions reduced or eliminated skin marking, citing simplified workflows and reduced setup time. Many respondents observed that SGRT implementation reduced both setup and treatment times for breast/chest, abdomen/pelvis and extremity procedures. SGRT has been widely embraced in Japan, offering notable clinical and workflow benefits. However, because participation in this survey was voluntary, the results may overrepresent institutions with greater awareness or adoption of SGRT. Greater standardization, broader insurance coverage and ongoing technological advancements are essential to fully realize its advantages.
