MRI Guided Brain Stimulation without the Use of a Neuronavigation System

Processing of a path retrieved from a POI drawn on a surface mesh generated by Brain Voyager. (a) The randomized order of vertices provided by the Brain Voyager output. (b) The same vertices after reordering. The jagged path resulting from the triangulation of the mesh is apparent. (c) A curve fitted to the vertices (in dashed green) allows the length of the path to be accurately calculated. The axis values are normalized POI vector coordinates in 3D.
