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