Abstract

Interstitial Photodynamic Therapy (IPDT) is a promising form of treatment of deep-seated and bulky malignant tumors, based on the lethal cell response to the photochemical reactions when drug is light activated in presence of oxygen. In order to accomplish an effective internal illumination, laser sources are preferably used because of two important reasons: the monochromatic light can be confined to the narrow absorption band of the drug and the laser beam is easily focused into optical fibers. In this work the development of a diode-laser-light-source is presented. The system is tuned by temperature to get a better match in the 5-ALA absorption band. This system also comprises a trifurcated fiber system to accomplish interstitial illumination.
