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...
A new methodology for assessment of pectus excavatum correction after bar remov...
Fonseca, João Luís Gomes; Vilaça, João Luis Araújo Martins; Henriques-Coelho, Tiago; Direito-Santos, Bruno; Pinho, António C.M.; Fonseca, Jaime C.Purpose: The objective is to present a new methodology to assess quantitatively the impact of bar removal on the anterior chest wall, among patients with pectus excavatum who have undergone the Nuss procedure, and present a preliminary study using this methodology. Methods: We propose to acquire, for each patient, the surface of the anterior chest wall using a three-dimensional laser scanner at subsequent time ...
