METHOD FOR AUTOMATED SEGMENTATION OF AN ARTERIOVENOUS MALFORMATION

Abstract: a method of processing image data for automated segmentation of an arteriovenous malformation includes obtaining a graph representation, combining nodes of the graph representation, determining a node or combined node with a highest number of direct connections to the node or combined node as the origin node, and combining nodes connected directly to the origin node. the method includes combining, with the origin node, a branching node connected to the origin node if it fulfills: the branching node is connected directly to precisely three nodes, and the branching node is connected directly or indirectly to a further branching node that is connected directly to at least four nodes. the indirect connection includes one or more nodes that are each connected directly to precisely two nodes. the method includes carrying out the method again, beginning with the combining of the nodes, if nodes are combined with the origin node.
