Microwave imaging and microwave induced thermoacoustic tomography

Breast cancer imaging by microwaves has been investigated intensively over the past two decades due to the potentially high electrical contrasts between malignant tumors and normal breast tissue, but so far clinically successful systems have been rare. We will describe challenges in achieving such a system, and ways to improve the resolution of microwave imaging. We will also report on our recent progress in microwave induced thermoacoustic tomography (MITAT) for breast imaging.
