Daily quality assurance, system and procedure‐specific commissioning of a bore‐based optical surface imaging system for surface‐guided radiotherapy (SGRT)

Key Points

• This research aims to implement and assess the commissioning of a bore-based optical imaging system for surface-guided radiotherapy.
• Developed a soft collision QA without daily calibration for 2 weeks.
• Updated inBore camera position by 2 cm to the bore front.
• Ensured SGRT-IGRT couch-shift consistency.
• Established a baseline performance of less than 0.2 mm drift.
• Commissioned a breast DIBH SGRT procedure with manual beam gating.
• Achieved successful implementation of the AlignRT inBore systems.
• Demonstrated baseline performance with minimal drift (< 0.2 mm).
• Achieved gating accuracy measured at 0.6s ± 0.2s.
