TECHNIQUES OF EVALUATION OF HEMOGLOBIN OXYGEN SATURATION IN CLINICAL OPHTHALMOLOGY

Autor: S. Yu. Petrov, A. A. Antonov, I. A. Novikov, T. A. Savelieva

Publikováno v: Biomedical Photonics, Vol 5, Iss 4, Pp 35-43 (2017)

Oxygen content in body fluids and tissues is an important indicator of life support functions. A number of ocular pathologies, e.g. glaucoma, are of presumable vascular origin which means altered blood supply and oxygen circulation. Most oxygen is tr

Optimization of energy parameters for laser-induced PDT of cervical tissues using numerical simulation and fluorescent monitoring

Autor: P M Alekseeva, K T Efendiev, T A Savelieva, A S Moskalev, R Steiner, V B Loschenov

Publikováno v: Laser Physics. 33:065602

The main problem in the photodynamic therapy (PDT) of tumors is insufficient light exposure to tissue or the appearance of undesirable surface effects. The reason is the irregular distribution of the absorbed light dose by depth. The influence of the
