Comparison of intra-operator variability on US to CT shifts. (a) An operator effect was observed in the intra-operator variability (shift standard deviation) in seroma shift determination. (b) Differences between mean US shifts for each operator and the CT shifts calculated by a single RO demonstrate that the operators with the least variable US results also correlate better with the CT results.
