dc.description.abstractHemodynamic information has proven valuable for analysis of cardiovascular diseases. Aberrant blood-flow patterns,for instance, often relate to disease progression. Magnetic resonance imaging enables blood-flow measurementsthat provide three-dimensional velocity fields during one heartbeat. However, visual analysis of these data ischallenging, because of the abundance and complexity of information. Explicit feature extraction can facilitate thepattern characterization, and hence support visualization techniques to effectively convey anomalous flow areas.In this work, we improve on existing pattern matching methods that characterize blood-flow patterns in volumetricimaging data. To this end, we propose a set of helical and vortical patterns that can be parameterized by a singlevariable. The characterization performance is validated on both synthetic and imaging blood-flow data. Moreover,we present a comprehensive visualization based on the pattern matching results, enabling semi-quantitativeassessment of the patterns in relation to the cardiovascular anatomy.en_US
