Abstract: The invention relates to a method of detecting the displacement of individual brain areas and to the presentation thereof on a display for guaranteeing optimal planning of an operation, said displacements being caused by tumor 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 tumor 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 tumor 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 tumor. 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 tumor as well as the detected displacements are subsequently inserted into a stereotactic atlas.

Abstract: NMR spectroscopy is increasingly used for the determination of the structure of proteins. According to the invention cross-signal pattern search masks are used for the joint evaluation of the 3D triple resonance experiments as well as the amino acid type-specific 2D spectra. All signal peaks due to an amino acid or a group of amino acids whose exact sequence has previously been derived from the protein sequence and forms the basis for the specific pattern recognition can be detected and evaluated jointly by means of pattern recognition with the aid of the cross-signal pattern search masks according to the invention. The invention permits a fully automated assignment of the signal peaks present in the various spectra to the magnetically active nuclei of the protein.

The image of the tumor as well as the detected displacements are subsequently inserted into a stereotactic atlas.
