The Fraunhofer Institute for Medical Image Computing MEVIS in Bremen has developed a new procedure which takes into account the uncertainties of the imaging, modeling and reconstruction analyzed individually and in the reconstruction of patient data.
The method makes it possible to determine a safe distance to the nerve pathways in the brain exactly.
In addition, the reconstructed data is determined, so the surgeon can gain information about the situation and the progress and possible intersections to allow the fiber tracts and separation distances to construct the neural pathways with.
Including the measurement, reconstruction and modeling errors, the exact local displacement of fiber tracts by the space-occupying tumor is calculated.
Thus, the neurosurgeon can access route and can determine how far the tumor and an additional safety margin may be cut without hurting nerve fiber tracts and damage to important areas of functioning without irreversible.
The software wizard will be further developed and used in future in the neuronavigation during an operation, so that the surgeon during an operation supplied with current information and can compare with the design data.
