| Popis: | The problems and possibilities of passive thermoacoustical tomography are discussed. Algorithms for reconstruction of internal temperature in the human body are proposed. These algorithms take into account heat transfer and blood circulation and the absorption factor, obtained previously. The results of reconstruction of deep temperature in the human hand in simulations with the medium with a heated object are reported. These results support the possibility of the correlation measurements of the thermal acoustic radiation. Such measurements allow the information on ultrasound absorption by the object under study to be obtained and open the way to the development of a passive acoustic tomography system using a priori information on the absorption factor. |
