Biomedical Optics in Otorhinolaryngology: Head and Neck Surgery gives an overview of current technology in biomedical optics relevant to the field of Otorhinolaryngology and head and neck surgery. It provides a comprehensive source of knowledge for researchers and active clinicians seeking information on the principles and practical use of novel diagnostic and therapeutic technology. While most books focus exclusively on laser surgery, which has been largely unchanged for the past 15 years, optical diagnostics and head and neck PDT (photodynamic therapy) are usually entirely overlooked. This book contains a basic introduction into the physics of light and its propagation, lasers and low-coherent light sources, and photon-tissue interaction in relation to therapeutic and diagnostic use. The principles of various imaging techniques are also discussed ( i.e. optical coherence tomography in its variations), as well as the principles and practice of lasers for surgical use on the therapeutic side.
