Abstract:
Magnetic resonance imaging and spectroscopy has it’s basis in the quantum mechanical properties of components of an atom’s nucleus, thus its large initial application in chemical engineering. Detection relies on large electromagnets (resistive and superconducting (and hence disciplinary research in Materials Science)), large energy pulsed magnetic fields (Teslas) at the kilohertz and radiofrequency (MHz) frequencies, signal processing/digitization, and numerical algorithms (e.g., Fourier transforms, thus capturing much of the electromagnetic spectrum found in electrical engineering and computer science. The forces and torques generated within the systems during normal operations can be several MegaNewtons and are both static and variable necessitating novel designs to manage the generated forces as well as particular heat management challenges that involve Mechanical Engineering. The spatial resolution can be on the order of microns in biological samples. These systems can weigh up to 100,000 pounds and thus provide unique installation challenges as system vibrations must be 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 via research in biomedical engineering, oftentimes requiring the use of novel types of injectable contrast agents with macromolecular and chelating molecules structures that might be developed by faculty in Macromolecular Sciences. The basics of MRI and the intersection of each of these engineering disciplines in the development of MRI over the past 40 years will be the focus of this talk.
