Comparison of the accuracy of the adapted contours with the static peak-exhale (PE) and mid-ventilation contours (MV) via centroid distance (CD) and Dice similarity coefficient (DSC). 5th and 95th denote the 5th and 95th percentile, respectively. All values are averaged over all investigated combinations of imaging parameters. Kidney and gallbladder contours were compared to the ground truth contours for all phases of the second and third scan, while the lung tumor contours were compared to the contours of the eight breathing phases of the single scan other than the peak-exhale and mid-ventilation phase.
