STUDY ON ELECTROMAGNETIC CHARACTERISTICS FOR DEVELOPMENT OF MICROWAVE MEDICAL IMAGING SYSTEM

Abstract

<p>The work consists of a detailed study carried out on the characteristics of the development of a microwave medical imaging system (MMIS) and aims to understand its operation. The scope of this work comprises the electrical characteristics of healthy and malignant biological tissues, the dielectric characteristics of the human chest region, the interactions of electromagnetic waves (EWs) with tissues, as well as the functioning of the MMIS and the emission/repetition of electromagnetic signals. As a result, it was found that malignant tissues have a higher dielectric constant, which generates greater reflection intensity and that there is a need to process the reflected signals, which arrive full of noise, to synthesize the image using frequencies in the microwave range. </p&gt
