- The clinical use of surface imaging has increased dramatically, with demonstrated utility for initial patient positioning, real-time motion monitoring, and beam gating in a variety of anatomical sites. The Therapy Physics Subcommittee and the Imaging for Treatment Verification Working Group of the American Association of Physicists in Medicine commissioned Task Group 302 to review the current clinical uses of surface imaging and emerging clinical applications. The specific charge of this task group was to provide technical guidelines for clinical indications of use for general positioning, breast deep-inspiration breath hold treatment, and frameless stereotactic radiosurgery. Additionally, the task group was charged with providing commissioning and on-going quality assurance (QA) requirements for surface-guided radiation therapy (SGRT) as part of a comprehensive QA program including risk assessment. Workflow considerations for other anatomic sites and for computed tomography simulation, including motion management, are also discussed. Finally, developing clinical applications, such as stereotactic body radiotherapy (SBRT) or proton radiotherapy, are presented. The recommendations made in this report, which are summarized at the end of the report, are applicable to all video-based SGRT systems available at the time of writing.

- Introduction: Surface Guided Radiation Therapy (SGRT) is being increasingly implemented into clinical practiceacross a number of techniques and irradiation-sites. This technology, which is provided by different vendors, canbe used with most simulation- and delivery-systems. However, limited guidelines and the complexity of clinicalsettings have led to diverse patterns of operation. With the aim to understand current clinical practice a surveywas designed focusing on specifics of the clinical implementation and usage.Materials and methods: A 32-question survey covered: type and number of systems, quality assurance (QA),clinical workflows, and identification of strengths/limitations. Respondents from different professional groupsand countries were invited to participate. The survey was distributed internationally via ESTRO-membership,social media and vendors.Results: Of the 278 institutions responding, 172 had at least one SGRT-system and 136 use SGRT clinically.Implementation and QA were primarily based on the vendors’ recommendations and phantoms. SGRT wasmainly implemented in breast RT (116/136), with strong but diverse representation of other sites. Many (58/135) reported at least partial elimination of skin-marks and a third (43/126) used open-masks. The most commonimaging protocol reported included the combination of radiographic imaging with SGRT. Patient positioning(115/136), motion management (104/136) and DIBH (99/136) were the main applications.Main barriers to broader application were cost, system integration issues and lack of demonstrated clinical value.A lack of guidelines in terms of QA of the system was highlighted.Conclusions: This overview of the SGRT status has the potential to support users, vendors and organisations in thedevelopment of practices, products and guidelines.
