摘要：Microwave imaging (MWI) techniques have shown compelling advantages in medical imaging compared with conventional imaging methods. For instance, MWI systems are less expensive and conveniently more 

portable than most magnetic resonance imaging (MRI) systems. The MWI image resolution may have more 

specificity than the ultrasound images. Because of the non-ionization, MWI does not have the safety concerns 

of  X-ray and positron emission tomography (PET). Therefore, multiple MWI prototype systems have been 

successfully implemented for medical imaging purposes, including medical diagnosis and therapy monitoring. Despite the increasing number of studies in quantitative MWI systems, the vast majority of these works are still theoretical or simulation based, and realization of these systems in an experimental setting has not been proven or adopted widely. It is still difficult to monitor target region in large human organs (such as liver, brain, breast) with limited measurements at a single frequency point. The efficiency of the prototypes cannot meet most medical near-real-time or real-time requirements for medical imaging and therapy monitoring. In this presentation, a new quantitative MWI prototype system is introduced to evaluate biomedical targets and monitor the thermal therapy. New coupling fluid, quad-band antenna array, inverse solver are integrated in the system for 3D 

high-resolution imaging and real-time monitoring.
