Biophotonic devices and technologies in problems of medical diagnostics

The standard diagnostic procedures preceding the start of treatment, aimed to identify the disease as well as to understand its aetiology and pathophysiological features in a particular patient, include blood tests, X-ray imaging, etc. As a rule, a significant part of these investigations is performed using optical methods. Since soft biological tissues are lightscattering media that transmit light inside themselves, optical methods also make it possible to examine tissues inside the body without violating its integrity (noninvasively, in vivo, in situ).
