Multifunctional Laser Noninvasive Spectroscopic System for Medical Diagnostics and Metrological Provisions for That

摘要

This paper describes a new multifunctional laser noninvasive diagnostic system (MLNDS) for medicine. In a single hardware MLNDS combines 3 different in vivo laser diagnostic techniques: Laser Doppler Flowmetry, Laser Fluorescent Diagnostics and Reflectance Tissue Oximetry. All these methods together allow a doctor to evaluate more exactly and in vivo a functional condition of soft tissues, especially to study the finenesses of respiratory and blood microcirculation processes in a skin and mucosa. The complex complementary diagnostics turns out to be more powerful than a trivial sum of isolated one. To produce more precise measurements a number of problems of metrological providing for that have been studied as well as a set of simple, reproducible and photostable calibration gauges with tissue-like optical properties has been created.
