Abstract:
The aim of this research is to advance image resolution in magnetic resonance imaging (MRI) via the introduction of special materials. Brightening phenomena have been observed in recent MRI scans involving the implementation of pads made of high permittivity materials. The scope of this research is to define the image brightening mechanism contributed by the materials through analysis of the data and application of phenomenological modeling. Our studies invoke the conepts of impedance optimization, superposition of internal reflections, and magnetic field propagation. Our aim is to progress the resolution of MR images by material enhancement.
