Principle of Obtaining Images in Correlation Acoustic Thermotomography with Focusing

Аннотация

A procedure is described for reconstructing separately the spatial distributions of the absorption coefficient, speed of sound, and the intrinsic temperature of an investigated object by means of acoustic thermotomography. The use of radiation focusing in combination with additional anisotropic backlighting is required. Objects with arbitrary shape, small wave sizes, and arbitrary sizes are considered.
