Abstract

The paper presents a technique for detecting detecting left atrium as well as the pulmonary veins of the left atrium by tracing out their centerlines. A vessel detection and traversal process is initiated from the venoatrial junctions. Pulmonary veins draining into the left atrium via these junctions are thus detected, also enabling the detection of the ostium. Ostial diameters are measured from the detected centerlines using a best-fitting ellipse. Quantitative validation of the techniques are reported on nine patient datasets. In only two of the datasets, mis-detections were identified. The ostial diameter measurements indicated an error of at most 5% in most of the cases. We envisage that the techniques presented will facilitate in planning the non-pharmacological treatment of atrial fibrillation using radio-frequency ablation therapy.
