Abstract
Conventional coronary angiography has been the current gold standard for evaluation of coronary stenosis severity. However, this is an invasive procedure, based on ionizing radiation (X-Ray) and dependent of nephrotoxic contrast agents. In the past three decades, echocardiography has emerged as an important medical image modality in Cardiology. With the advent of microbubble-based contrast agents and array transducers, 3D-echocardiography now presents itself as a relative low-cost, non invasive and non ionizing alternative method to visibilize arteries and their dynamics. This paper investigates some segmentation techniques to emphasize and isolate epicardial coronaries in tridimensional microbubblecontrasted echocardiographic images, since available computational tools do not provide adequate processing.
