Acoustothermometrical measurements were carried out for the model biological objects. As model objects we used the plasticine bodies placed in the water. In the experiment the model objects were being heated up and cooled down. The temporal dependences of their acoustobrightness temperatures were obtained and the reconstruction of the 2-D temperature distribution was made. The position, size and temperature of the thermal source were detected. The reconstruction error was about 1-2 mm for the position and size and about 1 K for the temperature. These results were obtained when the measurement time was about 50 s. As well we carried out the acoustothermometrical control during the laser hyperthemia of the mammary gland. The medicine procedure was continued 10 min and the maximum gland acoustobrightness temperature was increased at about 7 degrees.

A radiative transfer theory for electromagnetic wave multiple scattering in dielectric random media with effects of near fields is presented. The theory is based on Sommerfeld-Weyl angular spectrum decomposition of wave amplitudes and technique of Dyson and Bethe-Salpeter equations for the ensemble averaged angular spectrum amplitudes and the coherence matrix of angular specrum amplitudes, respectively. We derive the four integral equations' system, for two autocoherences of waves propagating forward and backward with respect to embedding parameter into the medium slab and two cross-coherences of evanescent waves decaying in opposite directions. In so doing the equations for autocoherences describe basically the usual radiative transfer with wave intensity multiple scattering by random inhomogeneities (scatterers) and free path between them. In the contrary the equations for cross-coherences demonstrate a new effect of elementary evanescent waves' virtually exciting inside an inhomogeneity in pairs of opposite decaying derections and contribution of these evanescent pairs to wave energy flux.
