Description
| - The problem most frequently encountered in the practical processing of medical images consists in the lack of instruments enabling machine evaluation of the images. A typical example of this situation is perfusion analysis of brain tumor types. The first and very significant step lies in the segmentation of individual parts of the brain tumor; after segmentation, the rate of penetration by the applied contrast agent is observed in the parts. The common method, in which a high error rate has to be considered, is to mark these tumor portions manually. The quality of brain tissue segmentation exerts significant influence on the quality of evaluation of perfusion parameters; consequently, the tumor type recognition is also influenced. The authors describe classification methods enabling the segmentation of images acquired via magnetic resonance tomography. During the edema segmentation, we obtained the following data: sensitivity 0.78+-0.09, specificity 1.00+-0.00, error rate 0.45+-0.24 %, surface overlap
