Scanning Microwave Induced Acoustic Tomography

Abstract

Since the grant was awarded in October 2000, we have published three peer-reviewed journal articles, published one conference proceedings article, delivered 16 invited talks, and graduated one M.S. student. This research has been successful and rewarding. We are well prepared to continue the project with greater successes. Until cancer is eradicated by preventative measures, the grand challenge in cancer research is early-cancer detection because the cure rate of cancers is much improved if they are detected early. Cancerous breast tissues are found to be 2-5 times more strongly absorbing than surrounding normal breast tissues in the microwave, which has been attributed to an increase in bound water and sodium within malignant cells. The combination of ultrasound and microwave has provided us a unique opportunity for early-cancer imaging with high resolution and high contrast. We have made significant technical progress in thermoacoustic imaging including imaging configuration, data processing, and reconstruction. We have successfully imaged biological tissue with high resolution and high contrast. We look forward to meeting this grand challenge.
