Implementation of surface-guided radiotherapy for motion management in liver SBRT: A scoping review and clinical workflow development

Key Points

• This research aims to evaluate the use of surface-guided radiotherapy (SGRT) for managing patient motion during liver stereotactic body radiotherapy (SBRT).
• Conducted a scoping review to assess existing literature on SGRT for liver SBRT.
• Developed a clinical workflow for implementing SGRT in treating patients with inconsistent breath-holding.
• Analyzed the effectiveness of noninvasive positioning and intrafraction monitoring techniques.
• SGRT was found to be a feasible motion management strategy for liver SBRT.
• It enabled reliable breath-holding and allowed accurate treatment delivery.
• Further studies are needed to confirm the reproducibility of breath-holding amplitude and its clinical outcomes.
