Fig. 4.

Distance to closest point boxplots of the different metrics: (a) mean, (b) median, and (c) Hausdorff distance. Inter and intra-operator variability plots are shown in pink and blue, respectively. Different boxplots are presented to visualise the different structures: left atrial body (LA), left atrial appendage (LAA), as well as the pulmonary veins left superior (LSPV) and inferior (LIPV), and right superior (RSPV) and inferior Mean (a) and median (b) of the distance to closest point are overall under 1 mm.
