Correlation plots and best fit lines showing the relationship between manual and automatic segmentation mean doses for the whole heart (WH), left atrium (LA), right atrium (RA), left ventricle (LV), right ventricle (RV), and left anterior descending artery (LAD). The maximum dose to the LAD calculated by each method was also compared. The error bars define the range in dose values observed for 100 realizations of a 5 mm shift in the contours. Best fit lines were calculated separately for left- and right- sided treatment. For the LAD left-sided treatment case, a single outlier was excluded from the linear regression as it was determined to unduly influence the regression.
