An automated method for lumen and media-adventitia border detection in a sequence of IVUS frames.

An automated method for lumen and media-adventitia border detection in a sequence of IVUS frames.

In this paper, we present a method for the automated detection of lumen and media-adventitia border in sequential intravascular ultrasound (IVUS) frames. The method is based on the use of deformable models. The energy function is appropriately modified and minimized using a Hopfield neural network....
