Editado por Luiz H. de Figueiredo e Jonas de Miranda Gomes.  aThis paper describes the detection of an artery by hough transform, developed on a PC-based system which hosts a transputer-based harlequin framestore. This work is part of a programme of research in ultrasound image aimed to translate feature extraction into a cost effective implementation. The project aims to provide three dimensional vascular reconstruction via non-invasive ultrasound, to improve surgical planning and diagnosis of arterial disease.1 aNIXON, M.  tIn: SIMPÓSIO BRASILEIRO DE COMPUTAÇÃO GRÁFICA E PROCESSAMENTO DE IMAGENS, 6., 1993, Recife.
