Latest Trends in Microwave Bioimaging & Diagnostic Technology

Deepshikha Shukla

Future trends in medical applications of microwave technique and technology can be seen in development of latest diagnostic and imaging methods based on high frequency EM field. Interactions of EM field with biological systems are utilized in the area of therapy (oncology, physiotherapy, urology atp.) Applications include biomedical imaging concealed weapon detection, through-the-wall imaging, non-destructive testing and evaluation. There is an emerging biomedical imaging modality with great potential for non-invasive assessment of functional and pathological conditions of soft tissues . This paper presents a review of researches and focuses on various potential clinical applications of MWT. There is a very high dielectric contrast between bones and fatty areas compared with soft tissues. MWT is applicable for extremities imaging, breast cancer detection, diagnostics of lung cancer, brain imaging and cardiac imaging. The lower frequency up to 1GHz is applicable for imaging larger objects, for example wholebody imaging. Higher frequencies (up to 3–4 GHz) are applicable (in terms of penetration) for extremity imaging, producing higher resolution images.
