Computerized Tomography with Radon Transform using Microwaves and Electrostatics

Abstract

Imaging of the human body is essential for diagnosing disease, especially cancerous growth within the human body and invisible to direct human observation. In this work, we present a microwaves-based imaging tomography technique using Radon Transforms. While such a technique had been attempted in the past, here, and in a drastic departure from these earlier attempts, we employ microwaves such that the dimensions of the body being imaged is significantly smaller than the wavelength in free space. Thus, the imaging concept employed here is independent of the classical diffraction limit. Additionally, we show that a high-resolution image can be obtained using electrostatic fields. Numerical results will be presented to demonstrate the viability of the proposed modality.
