Coronary Artery Centerline Extraction in Cardiac CT Angiography Using a CNN-Based Orientation Classifier

Accurate information about the geometry and topology of a patient ’s vasculature is crucial for many medical applications. In patients with suspected coronary artery disease, information about the cardiac vasculature may be obtained non-invasively using a cardiac CT angiography (CCTA) scan (Leipsic et al., 2014). A typical first step in the analysis of CCTA sca ns is the extraction of coronary artery lumen centerlines, which allow multi-planar reconstructions that facilitate stenosis detection and plaque identification.
