Thermo-acoustic imaging for different breast tissues in microwave induced thermo-acoustic tomography system

Microwave induced thermo-acoustic tomography (MITAT) combines the advantages of both ultrasound imaging and microwave imaging. In this paper, a secure and accurate MITAT system has been developed. Aiming to demonstrate the capability of MITAT in breast cancer detection, experiments by using real breast tissues and breast tumor specimen have been performed. The results show the high contrast of the developed MITAT system. The distinguishing ability for tumors at different clinical stages has been studied. The experimental results show that developed MITAT system can distinguish not only the normal and cancer specimens but also the cancer tissue specimens at different clinical stages.
