Patent ID: 7043068

Claim:
A method of determining displacements of brain areas as a result of tumor formation and of their presentation on an image screen utilizing stereotactic atlases characterized by determining by means of known physical correlations, particularly Hooke's law, a displacement vector u ( r ) for each point of mass of a brain area (P 1 , P 2 , P 3 , P n ) which in an initial state was located at a position described by a position vector (r 1 , r 2 , r 3 , r n ) where the tumor ( 3 ) is now located, which displacement vector may be unambiguously defined by two parameters b, c, whereby the parameters b, c may be derived from the boundary conditions tumor size and tumor type and the displacement vectors u ( r ) are subsequently mathematically calculated and a new position vector ( r 11 , r 22 , r 33 , r nn ) is calculated for each point of mass of a brain area (P 1 , P 2 , P 3 , P n ) as a result of the displacement, thereafter inserting the image of the tumor ( 3 ) as well as the determined displacements with the new position vectors ( r 11 , r 22 , r 33 , r nn ) which took place as a result of the tumor formation, into an anatomic atlas so that the brain areas characterized by the displaced points of mass (P 11 , P 22 , P 33 , P nn ) are now displayed in the actual positions.
