Carbon nanotubes (CNTs) enhanced breast tumor detection have been proposed to mitigate the low contrast between the tumor and the glandular tissue in the microwave induced thermo-acoustic tomography (MITAT). In this paper, we discuss an iterative reconstruction method (IRM) to tackle the issue of defocusing due to the acoustic heterogeneity of the dense breast underlying the CNTs-enhanced MITAT. The...
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...
Microwave-induced thermal acoustic tomography (MITAT) is an innovative technique to image biomedical tissues based on their electric properties. It has the advantages of both high contrast and high spatial resolution. Image reconstruction method in MITAT is always a critical issue. In this paper, a CS-MITAT (CS: compressive sensing) imaging method is proposed. Compressive sensing (CS) is a recently...
