Conclusion:

When modifying plans, representing linac errors, similar values of the change in PTV mean dose were obtained with PerFRACTION and Eclipse. If a standard gamma passing rate criterion is used, PerFRACTION is more sensitive to detect linac errors than experimental measurements.

Keywords: PerFRACTION, sensitivity
