摘要：
A scheme of acoustic correlation thermotomography is considered for a medium that is inhomogeneous in temperature, absorption coefficient, and phase velocity of ultrasound. It is demonstrated that, with the use of an external "illuminating" field (of thermal origin or generated artificially), it is possible to separately reconstruct the distributions of all aforementioned parameters.
