Abstract
Application of optoacoustic methods in biomedical research
Incoming article date: 29.11.2017Methods based on the thermo-optoacoustic effect in a liquid for conducting biomedical research are considered in the work. The mechanisms participating in the formation of the optoacoustic signal are considered. Thermo-opoacoustic effect leads to the excitation of ultrasonic waves when absorbing a variable light flux. Numerical methods for calculating the optoacoustic effect that can be applied to energy calculations and conditions of a source with arbitrary geometry, to the construction of a temporal profile of laser radiation, to linear scanning of a laser source and tomography are considered.
Keywords: optoacoustics, optoacoustic waves, biofluids, spherical sources, absorption.
