About the speaker:
Ilya Turchin (Ph.D.) is the Head of the Department for radiophysical methods in medicine at the Institute of Applied Physics of RAS and is an expert in optical diagnostics for biomedical applications (diffuse optical spectroscopy, fluorescence imaging, optoacoustic). He has over 16 years of experience as a primary investigator in optical imaging and translating optical techniques to clinics. 
Abstract:
Diffuse optical spectroscopy (DOS) and optoacoustic (OA) imaging are based on selective light absorption by various tissue chromophores (oxy-, deoxyhemoglobin, water, lipids, melanin) and benefit from high molecular sensitivity. DOS evaluates blood and water content and tissue oxygenation by analyzing diffusively scattered photons propagated through biological tissue at different wavelengths. OA imaging methods are based on probing tissue with a nanosecond laser pulse and recording an ultrasonic wave resulting from the local thermoelastic expansion of tissues. OA combines the advantages of optical methods with high molecular sensitivity and ultrasonic methods with a high spatial resolution providing functional and structural information on biological tissue. The recent advances in DOS and OA methods for biotissue diagnostics will be presented.
