Figure 3From: Intraplaque hemorrhage is associated with higher structural stresses in human atherosclerotic plaques: an in vivo MRI-based 3d fluid-structure interaction study Schematic drawing demonstrating the node-type assignment method for nodal point on lumen surfaces. Node type was defined as the closest component the node was covering, or hemorrhage if it was inside the lipid. Zones 1 & 3 are lipid zones; Zone 2 is a normal wall zone; Zone 4 is a hemorrhage zone.Back to article page
