Automated segmentation of the atrial region and fossa ovalis towards computer-a...
Morais, Pedro; Vilaça, João; Queirós, Sandro; Marchi, Alberto; Bourier, Felix; Deisenhofer, Isabel; D'hooge, Jan; Tavares, JoãoBackground and objective: Image-fusion strategies have been applied to improve inter-atrial septal (IAS) wall minimally-invasive interventions. Hereto, several landmarks are initially identified on richly-detailed datasets throughout the planning stage and then combined with intra-operative images, enhancing the relevant structures and easing the procedure. Nevertheless, such planning is still performed manually...

A competitive strategy for atrial and aortic tract segmentation based on deform...
Morais, Pedro André Gonçalves; Vilaça, João Luis Araújo Martins; Queirós, Sandro Filipe Monteiro; Bourier, Felix; Deisenhofer, IsabelMultiple strategies have previously been described for atrial region (i.e. atrial bodies and aortic tract) segmentation. Although these techniques have proven their accuracy, inadequate results in the mid atrial walls are common, restricting their application for specific cardiac interventions. In this work, we introduce a novel competitive strategy to perform atrial region segmentation with correct delineation...
