Adaptation of structure size or wall thickness by local offset operations. a 3D model of the aorta. b Coronaries as segmented from original CT scan. c Wall thickness analysis largely showing values < 1mm (critical value chosen for this example) at the coronaries. d Marking of the coronary surface to define the region for local size adaptation. e Application of a local offset operation to shift the marked triangles towards the outside and, thereby, dilate the coronaries. Post-processing of the transition area conceals surface modifications. f Renewed analysis shows wall thickness values > 1mm
