Abstract
Summary We propose a fully automate dm ethod for calculating vectorial wall shear stress (WSS) in-vivo based on 4D PC-MRI data. Background Wall shear stress (WSS) is the tangential force of flowing blood on the vessel wall. WSS directly influences remodeling of the vessel wall. Methods

Inward unit normal vectors were determined on the wall, after which a coordinate transformation was performed for each point at the wall such that the normal vector coincided with the z-axis of the transformed coordinate system
