Page 1: Magnetic Resonance Imaging

Abstract: Magnetic resonance imaging and spectroscopy has it’s basis in the quantum mechanicalproperties of components of an atom’s nucleus, thus its large initial application in chemicalengineering. Detection relies on large electromagnets (resistive and superconducting (and hencedisciplinary research in Materials Science)), large energy pulsed magnetic fields (Teslas) at the kilohertzand radiofrequency (MHz) frequencies, signal processing/digitization, and numerical algorithms (e.g.,Fourier transforms, thus capturing much of the electromagnetic spectrum found in electrical engineeringand computer science. The forces and torques generated within the systems during normal operations canbe several MegaNewtons and are both static and variable necessitating novel designs to manage thegenerated forces as well as particular heat management challenges that involve MechanicalEngineering. The spatial resolution can be on the order of microns in biological samples. These systemscan weigh up to 100,000 pounds and thus provide unique installation challenges as system vibrations mustbe minimized often necessitating placement on unique structural foundations designed by Civil Engineers.Biologically, they are used to detect pathology, measure blood flow, perform guided procedures viaresearch in biomedical engineering, oftentimes requiring the use of novel types of injectable contrastagents with macromolecular and chelating molecules structures that might be developed by faculty inMacromolecular Sciences. The basics of MRI and the intersection of each of these engineering disciplinesin the development of MRI over the past 40 years will be the focus of this talk.
