Aa. Anosov et al., Reconstruction of a two-dimensional distribution of the internal temperature of a model object by passive thermoacoustic tomography, ACOUST PHYS, 45(1), 1999, pp. 14-18
A two-dimensional distribution of the internal temperature of an object was
reconstructed using the method of passive thermoacoustic tomography by the
measurements of the acoustic brightness temperature at various angles. The
reconstruction was performed by using the least squares technique, the met
hod of elimination of nonphysical solutions, and the regularization accordi
ng to Tikhonov.
