Implementing log file-based patient-specific QA for VMAT plans: A comparative study of MobiusFX and measurement-based approaches.

Key Points

• The aim is to compare MobiusFX with traditional measurement-based methods for verifying VMAT plans.
• Conducted a comparative analysis of MobiusFX and measurement-based QA methods.
• Evaluated gamma passing rates at 3%/3 mm and 3%/2 mm criteria.
• Considered machine- and system-specific factors for implementation.
• MobiusFX exhibited interchangeable gamma passing rates with measurement methods.
• Both methods met the criteria for effective VMAT pretreatment verification.
• Importance of machine and system factors highlighted for clinical reliability.
