Combined opto-ultrasound method of tissue oxygenation and its application in medicine

摘要

The results of in vivo investigation of combined optical and ultrasound methods of tissue oxygenation and their application in medicine are presented. The optical method is based on the phenomenon of laser-induced photodissociation of blood oxyhemoglobin in cutaneous blood vessels. It is shown that this method provides an extraction of additional oxygen directly in the irradiation zone. The acoustic method enhances the efficiency of optically induced tissue oxygenation by improvement in the blood microcirculation. Some biomedical applications of the developed combined opto-ultrasound method of tissue oxygenation are discussed.
