Аннотация: Thermoacoustic tomography is a method for determining the spatial distribution of thetemperature of biological objects by receiving and processing their own thermalacoustic radiation. The intensiometric approach is based on the determination of thepower of thermoacoustic radiation. In the correlation approach the coherence matrix ofthe signals registered by the receiver system is processed. Statistical estimates arepresented that allow determining the sensitivity in the case of each of the approaches.These estimates are applied to a multichannel tomographic scheme that uses acousticfield focusing. The results of its numerical simulation and selection of parameters arepresented. It is possible to achieve an acceptable temperature sensitivity in the case ofeach of the approaches. The correlation approach requires more data acquisition time,but allows obtaining a better resolution and getting rid of mechanical scanning alongone of the spatial coordinates.
