"In stereotactic laser neurosurgery a tumor in the human brain is resected by a pulsed high energy laser beam. The laser beams for diagnosis and ablation of cancerous tissue are supplied through a probe. The whole resection is planned with a computer system. These planning data are based on previously obtained CT and MRT imaging. During the operation the complete process (diagnosis and resection) is guided and controlled by a computer system. One important part of the surgical system is the OligoChannel Spectrum Analyzer (OCSA), of which the principles and development are described in this work. The OCSA analyzes the autofluorescence spectrum of each observed tissue point in order to determine its kind. This is possible since autofluorescence spectra of healthy and cancerous tissue show characteristic differences. In contrast to commonly used techniques, the OCSA uses only a few detectors. By evaluation of the data obtained with the OCSA, an immediate decision can be made whether a specific tissue point should be ablated or not. To demonstrate the new technique, some results obtained with different tissue samples (human kidney and various mouse tissues) will be presented."^^ . "2003" . . . . . . . . "Klaus"^^ . "Greger"^^ .
