<p>The invention relates to a method for detecting displacements of individual brain areas and to the representation thereof on a display for guaranteeing optimal planning of an operation, said displacements being caused by tumour formation. According to the invention, a displacement vector is detected for each brain area which was situated at a defined location in the initial position where a tumour is located now. Said displacement vector defines the displacement of a brain area in the direction and the amount thereof, whereby said displacement is caused by tumour growth. Said vector is detected by means of two parameters (b and c) which can be derived from the size and the kind of the tumour. The displacement vectors are numerically calculated according to the formula ur=cr + br-2 after the two parameters have been detected. The image of the tumour as well as the detected displacements are subsequently inserted into a stereotactic atlas. The brain areas are displayed at the actual locations in the thus obtain image. Improved planning for carrying out operations can thus be guaranteed by means of said representation.</p> |
