and other large deviations were observed, such as a relative difference in volume close to 300%, DSC of 0.1 and HD of 90 mm (Figure 1 and 2).

Figure 1. Geometric and dosimetric comparisons between each automatic segmentation of the proximal bronchial tree and the corresponding manual contour (circles). All doses are normalized to the PD. The shape of the violins is the kernel density. In each violin, the central mark represents the mean, the white circle the median and the bottom and top of the shaded area the 25 th and 75 th percentiles. The bold numbers mark circles belonging to the examples in Figure 2. The numbers at the bottom represent the mean ± 1 standard deviation.
