A Dataset of Reconstructed Carotid Bifurcation Lumen and Plaque Models with Centerline Tree and Simulated Hemodynamics

carotid_bifurcation_database.zip contains 79 cases of left and right-side carotid bifurcations (152 inner wall models). For each case, inner wall (lumen) and plaque models were extracted from computed tomography angiography (CTA) scans. The models were segmented, reconstructed, and a centerline tree was created for each geometry using the CarotidAnalyzer pipeline. The geometries include varying degrees of internal carotid stenosis. Bifurcations with 100% stenosis were omitted, as the vessel is not discernible in the scan.

carotid_flow_database.zip contains hemodynamic flow simulations of the above models. Fluid data (velocity, pressure) and surface data (wall shear stress) are given in seperate files for each case. For each field, a systolic and diastolic time step are provided.
