Quality assurance of VMAT on flattened and flattening filter-free accelerators using a high spatial resolution detector.

CONCLUSIONS: The investigation on the use of solid-state detectors in combination with an inclinometer has demonstrated the capability to provide efficient and independent verification of DR, GS, and MLC leaf speed during dynamic VMAT delivery. Good agreement with machine log files suggests the detector/inclinometer system is a useful tool for machine-specific VMAT QA.
