Microwave-Induced Thermo-Acoustic Tomography (MITAT) is a promising technique in biologic tissue imaging. It has predominant advantages in both contrast and resolution compared with conventional microwave or ultrasound imaging system for malignant tumors. In this paper, an integrated prototype MITAT system is briefly introduced. And Time Reversal Mirror (TRM) imaging technique based on Pseudo-Spectrum Time Domain (PSTD) is also first time applied to MITAT system. Two tissue strips of porcine muscle are used as targets in the MITAT experiment to demonstrate the imaging potential of the system. TRM and Filtered Back-Projection (FBP) imaging results are both presented to compare the performance of the TRM and other imaging techniques in contrast and resolution for MITAT.
