Segmentation of Nidus – Brain AVM

A Cerebral Arteriovenous Malformation is an abnormal connection between arteries and veins. Normally the blood flows from arteries to veins through capillary bed. But patient having AVM, the capillary bed will be absent. The veins cannot handle the pressure of blood flowing from arteries to veins and it ruptures. The success of treatment by embolization in interventional Neuroradiolgy is highly dependent on the accuracy of the vessels visualization. In this paper, we have done segmentation of NIDUS using 3DRA for cerebral patients, so that the doctors can analyze and decide the mode of treatment. This method consists in Preprocessing step of image enhancement, Morphological operations, clustering are used to separate vessel pixels from background and artery pixels from vein pixels that will help to find path for track the blood flow.
