ABSTRACT
This chapter discusses the principle behind medical microwave imaging techniques by highlighting various medical applications. The chapter also discusses various imaging algorithms and an application of microwave imaging for detection of brain tumor. It presents an alternative imaging technique called microwave imaging for medical applications that uses nonionizing electromagnetic (EM) waves for imaging unlike ionizing X-rays. Medical imaging is usually a noninvasive tool to visualize the interior of the body of both healthy and diseased subjects. Microwave Imaging is an imaging technique using nonionizing EM signals in the frequency range of hundreds of megahertz to a few gigahertz. Microwave Imaging algorithms can be divided into two categories, namely, quantitative and qualitative. In general, quantitative algorithms are computationally and memory-wise demanding. Various research reports have shown the feasibility of using microwave imaging for applications such as brain stroke and tumor detection, breast cancer detection, heart imaging, and bone imaging.
