Extended Data Fig. 9: User segmentation variability and sensitivity analysis.

From: Blood flow modeling reveals improved collateral artery performance during the regenerative period in mammalian hearts

Extended Data Fig. 9

a, Radius measurements from 5 users of 16 segmentations over 3 vessels. The coefficient of variation is 16.7%. b, Sensitivity of pressure drop along the coronary tree to the radius of segmented vessels. Adult vessel radius was reduced by 20% and neonate vessel radius was increased by 20%.
