Highlights • Inter-fractional port positional errors can be larger than 1.5 cm.• Cumulative dosimetric effect of daily measured port errors is minimal.• Cumulative dosimetric effect of a systematic registration error can be significant.• Assigning the metal port tissue-equivalent density is not an adequate strategy.• Alignment of anatomical landmarks should be prioritized over port alignment.
