Modeling of non-contact thermoacoustic imaging

Microwave-induced thermoacoustic imaging (TAI) has been actively researched in the past decade and shown to be a promising non-ionizing technology for various applications, such as breast cancer imaging, brain imaging, renal calculi detection, and foreign body detection. TAI develops an image exhibiting internal structures of a lossy sample by exploiting generated acoustic waves from absorbed pulsed microwave energy in the sample owing to thermoacoustic effect (R. A. Kruger et al, Radiology, 216, 279–283, 2000).
