Sensitivity of gamma analysis on a 2D dataset
Yan et al, JACMP 2009
Gamma may be unable to detect
systematic errors that could/should
be corrected
Same gamma parameters give
different results in combination with
different detectors
Stricter gamma parameters are not
necessarily the most sensitive
Criteria for ‘flagging’ a dose
distribution mostly based on previous
clinical experience. Initial inaccuracies
in IMRT verification may have a long
lasting influence.
