Abstract :
Scanning thermoacoustic tomography based on microwave-induced thermoacoustic waves was studied. Two-dimensional images of ~50-mm thick biological tissue samples were obtained experimentally. The thermoacoustic signals were also simulated theoretically. The image resolution was significantly improved compared with purely microwave imaging
