Abstract

Overview

Microwave thermoacoustic tomography (MTT) is a unique imaging technology that utilizes microwave-pulse-induced thermoelastic pressure waves to create images. This method combines different physical and biological properties such as dielectric permittivity, specific heat, thermal expansion, and acoustic properties of tissues.

Findings

• Dual-Modality Imaging: MTT features the combined benefits of microwave and ultrasound imaging, offering high contrast through microwave absorption along with fine spatial resolution via ultrasound.
• Noninvasive Technique: MTT is recognized for its potential as a nonionizing and noninvasive diagnostic tool particularly beneficial for early breast cancer detection.
• Research and Development: Current research reviews the development of MTT imaging systems, discusses the science behind thermoelastic wave generation, and explores the prototyping and application in phantom models and clinical environments.

Conclusion

MTT imaging stands out as a promising approach in medical diagnostics, providing significant contributions to noninvasive and early detection technologies in healthcare, potentially revolutionizing the identification and management of breast cancer.
