Abstract

In recent years, microwave induced thermo-acoustic tomography (MITAT) has been of significant interest as a non-invasive medical imaging modality for biomedical applications. In virtue of the combination of microwave and acoustics imaging technique, it bears predominant advantages in both contrast and resolution. In this paper, three-dimensional MITAT imaging reconstruction using Time Reversal Mirror (TRM) technique is studied computationally. The forward and inverse phases are simulated by the Pseudo-Spectrum Time Domain (PSTD) method. Imaging results show that TRM technique well employs the information of wave propagation, can provides the MITAT system with high contrast and resolution three-dimensional image.
