<p>A lot of side effects accusers which the humans have suffered from a scan either by CT phrases, rays and magnetic resonance. Different methods were used to eliminate these affects depends on segmentation of vascular networks then represents it as a graph, where the intersection of the vessel as a vertex and the line between them as an edge. The place of the clot can be found by representing the weight of each edge as the amount of the blood in the vessel. Sign the place; if the amount is less than the normal flux that represents thrombosis. An algorithm in a graph theory is used to find the minimum distance, if more than one thrombosis exists to reach the nearest one and sign it alternately.</p>
