An argon-dye laser system for photodynamic therapy and diagnosis

An argon-dye laser system for the clinical application of photodynamic ther apy and photodynamic diagnosis is presented. Two out-patient treatment room s and three operating theaters are served by an argon-dye laser system whic h can be accessed by remote-control from each treatment room. The argon-dye laser offers a wide range of light wavelengths with sufficient energy for all kinds of photosensitizers and fluorescent substances. This report prese nts our experiences with the first remote-controlled laser configuration wh ich is being used routinely in clinical practice for photodynamic therapy a nd photodynamic diagnosis.
