Abstract
Schemes for improving the resolution of thermal tomographs using multielement receiving arrays are considered. Algorithms for processing the space-time correlation information are developed on the basis of the generalization of the high-resolution spectral analysis techniques in application to the problems of medical acoustic thermotomography in narrow-band and wide-band modes of operation. Special attention is given to Capon-type algorithms, which allow an increase in the spatial resolution of the fine structure of the power density distribution of thermoacoustic radiation sources.
