This dataset contains 62 cases of left and right-side carotid bifurcations (approx. 110 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 dataset contains models with varying degrees of internal carotid stenosis. Bifurcations with 100% stenosis were omitted, as the vessel is not discernible in the scan.
