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

MobiusFX showed interchangeable gamma passing rates with measurement-based methods at the 3%/3 mm and 3%/2 mm criteria, supporting its use as an alternative for VMAT pretreatment verification. Machine- and system-specific factors should be considered for reliable clinical implementation.
