Microwave Thermoacoustic Tomographic (MTT) Imaging

Abstract

Overview

Microwave Thermoacoustic Tomography (MTT) is an innovative imaging technique that utilizes microwave-induced thermoelastic pressure waves to generate images. The ability to discern properties such as dielectric permittivity and thermal expansion makes MTT a dual-modality system, combining aspects of microwave absorption and ultrasound resolution.

Findings

• High contrast imaging through microwave absorption.
• Fine spatial resolution from ultrasound technology.
• Nonionizing and noninvasive, ideal for early breast cancer detection.

Conclusion

The paper encapsulates the significant advancements in MTT imaging, detailing prototype design, image reconstruction, and applications in both phantom models and live subjects. This research furthers the potential of MTT as a safe, efficient tool in medical diagnostics.
