A novel method is presented for carotid artery vessel wall segmentation in computed tomography angiography (CTA) data. First the carotid lumen is semi-automatically segmented using a level set approach initialized with three seed points. Subsequently, calcium regions located within the vessel wall are automatically detected and classified using multiple(More)
Vessel image analysis is crucial when considering therapeutical options for (cardio-) vascular diseases. Our method, VAMPIRE (Vascular Analysis using Multiscale Paths Inferred from Ridges and Edges), involves two parts: a user defines a start- and endpoint upon which a lumen path is automatically defined, and which is used for initialization; the automatic(More)
This in vitro study evaluated the performance of 16-slice multidetector computed tomography (MDCT) in the assessment of carotid plaque components, with histology as the gold standard. Twenty-one specimens (n=21) were scanned and reconstructed after optimization of the protocol. Three corresponding MDCT images and histologic sections were selected from each(More)
