Computerized Tomography with Low-Frequency Electromagnetic Radiation

This work presents a new modality for human body imaging using low-frequency electromagnetic radiation and Radon Transforms. While the physics of electromagnetic energy transmission through human tissues is different from that of X-ray propagation in the same tissues, strong analogies exist between the two phenomena when the object to be imaged has dimensions significantly shorter than the wavelength. We demonstrate the validity of this modality using a simple but highly instructive numerical experiment involving an axially asymmetric body.
