Segmentación utilizando contornos activos (snakes) de imágenes de resonancia magnética del cerebro

Abstract

The segmentation of brain structures from Magnetic resonance imaging, is a very important tool in the diagnostic and follow up of several pathologies of the central nervous system. The obtaining of the contours of brain structures presents following problems: the great volume of data and noises in the images introduced by the acquisition equipment. During the past few years, the deformable models of active contours (Snakes) have been used for the segmentation of images and in special in images of Magnetic Resonance (R.M.), this document presents the automated segmentation of brain structures implementing Snakes like a fast and efficient solution for the obtaining of the contours of the objects with the purpose of helping in the medical planning. © Springer-Verlag Berlin Heidelberg 2007.
