Pulmonary contours in chest CT images are closed curves that may, in some cases, exhibit multiple concave and convex irregularities. In this paper we assess the quality of pulmonary contours obtained by several fully automated methods. A comparison among these contours and corresponding manually drawn reference contours was performed and several figures of merit were assigned to ea...
; As bolhas pulmonares com conteúdo aéreo podem ocorrer na sequência de enfisemas ou outras patologias, reduzindo a oxigenação sanguínea e, em caso de ruptura, podendo colocar ar na cavidade sub-pleural. Para realizar um diagnóstico médico e consequente tratamento, é necessário localizar e caracterizar morfologicamen...
In this paper we briefly introduce the mathematical foundations of deformable models, their properties and their usage in medical image segmentation. ; Neste artigo introduzem-se os fundamentos matemáticos dos modelos deformáveis de forma muito breve, descrevem-se as principais características de cada e faz-se uma revisão da sua utilização em c...
Pulmonary contour extraction from thoracic x-ray computed tomography images is a mandatory preprocessing step in many automated or semiautomated analysis tasks. This study was conducted to quantitatively assess the performance of a method for pulmonary contour extraction and region identification.Materials and methods ; http://www.sciencedirect.com/science/article/B75BK-4CYP37B-8/1/cd6c2e81a2efebfbc072409358...
