We present our numerical modeling approach to create a CFD\ndatabase that can guide stroke risk assessment\, including hemodynam ic shear risk\nmetrics. We investigate the multi-directional behavior of w all shear\nstress (WSS) based on specially\nconstructed longitudinal tange nt vectors using a center-line projection\napproach and present the utilit y of longitudinal WSS evaluation for\ndetecting opposing or transverse WSS in slow patient-specific flow. In\nour fluid-structure interaction model \,\nwe generalize the assumption of linear elasticity by a strain-dependen t\nelastic modulus that is consistent with laboratory measurements of\ncom pliance and distensibility. Finally\, we present the established\nworking pipeline to generate CFD\ndata for a large number of patient-specific geom etries. Created\nhemodynamic datasets can be used for visual atlases and c omparative\nanalysis or explored by neural networks.\n LOCATION:https://researchseminars.org/talk/NSCM/152/ END:VEVENT END:VCALENDAR
