| Research Directions:Magnetic resonance imaging (MRI) is a noninvasive technique employed in fields as diverse as materials science, chemistry, and medicine. Conventional MRI systems place the patient in very strong magnetic fields of 1 Tesla (20,000 times the Earth's field) or higher. High fields increase signal levels and therefore image quality, but this requires expensive superconducting magnet technology. The cost and constrained accessibility limit the applicability of MRI in many circumstances. Furthermore, high fields are not favorable for certain measurements, including those involving heterogeneous samples with large magnetic-susceptibility gradients. Ultra-low-field MRI will eliminate these problems. As well as reducing costs, low field imaging offers types of image contrast unavailable at the field strengths used in conventional scanners. The new type of low field system might find applications in clinic-based screening programmes. As part of our research into low field MRI we are developing magnet designs, pulse sequences and ultra-low noise receivers(OMRI, Squid,etc). | Education and Work Experiences:B.S.
