Abstract： Thermoacoustic imaging (TAI) is a promising hybrid modality for breast cancer detection and a number of other applications utilizing the advantages of microwave and ultrasound. Breast cancer causes the second highest morbidity and the highest mortality among women. Early detection is crucial to increasing the survival rate of breast cancer. Although some clinically available imaging modalities like mammography, magnetic resonance imaging (MRI) and ultrasound imaging have been extensively utilized for breast cancer diagnosis, their insufficiencies have motivated interests in developing complementary imaging methods.

Microwave-induced thermoacoustic imaging (TAI) has been researched in the past decade and shown to be a potential non-ionizing technique for the detection of breast cancer. TAI develops an image of the internal features of a dielectrically lossy sample by employing generated acoustic waves from absorbed microwave energy in the sample owing to thermoacoustic effect. Malignant tissues, usually embracing higher dielectric loss, absorbing more energy and emanating stronger acoustic waves than the surrounding healthy tissues, may be distinguished in the image. As a hybrid imaging modality, TAI is endowed with the unique merit of high contrast inherited from microwaves and excellent spatial resolution inherited from ultrasound. This talk will highlight some of the novel research our group has done and promising results have been achieved.

The Introduction of Hao Xin Professor：

Dr. Hao Xin, Professor of Electrical and Computer Engineering at the University of Arizona. He is named an Arizona Engineering fellow in Aug. 2013. He joined University of Arizona since August 2005 as an assistant professor. He was promoted to tenured associate professor in 2009 and to full professor in 2012. He received his Ph.D in Physics from Massachusetts Institute of Technology in February 2001. From 2000 to 2003, he was a research scientist with the Rockwell Scientific Company. He was a Sr. Principal Multidisciplinary Engineer with Raytheon Company from 2003 to 2005.

His primary research interests are in the area of microwave / millimeter wave / THz antennas, devices, circuits and their applications in wireless communication and sensing systems. His recent research activities have covered a broad range of high frequency technologies, including applications of new technologies and materials in microwave and millimeter wave circuits such as electromagnetic band gap crystals and other meta-materials, carbon nano-tubes devices, solid state devices and circuits, active or semi-active antennas, and passive circuits. He has authored over 200 referred publications and 14 patents (12 issued and 2 pending) in the areas of microwave and millimeter-wave technologies, random power harvesting based on ferro-fluidic nano-particles and carbon nanotube based devices. He is a senior member of IEEE and chair of the joint chapter of IEEE AP/MTT/EMC/COMM in Tucson AZ. He is a general co-chair of the 8th International Workshop on Antenna Technology. He also serves as an associate editor for IEEE Antennas and Wireless Propagation Letters.
