A novel audit methodology to improve detection of planning and delivery errors in passive motion management

Key Points

• This research aims to enhance the detection of errors in passive motion management through a novel auditing methodology.
• Implemented a new audit methodology for film measurements.
• Compared assessments with relaxed criteria versus eliminating motion in analysis.
• Utilized tighter gamma criteria for improved specificity.
• Specificity improved from 0.62 to 0.75 with one less false positive reported.
• Tighter gamma criteria demonstrated superior performance (4%/2 mm vs 5%/3 mm) with equal sensitivity.
