Magnetic Resonance Imaging (MRI) Research in Hawaii

October 9, 3:15pm - 4:45pm
Mānoa Campus, Watanabe Hall 112

Department of Physics and Astronomy Colloquium: Prof. Thomas Ernst, University of Hawaii, to speak on "Magnetic Resonance Imaging (MRI) Research in Hawaii."

Abstract:
Magnetic resonance imaging (MRI) and spectroscopy (MRS) use nuclear magnetic resonance to evaluate the structure, function, and physiology of the human brain in vivo. MRI affords high spatial and temporal resolution, is non-invasive and repeatable, and can be performed in children. However, motion continues to be a substantial problem in many MR studies, resulting in data with motion artifacts that may prevent accurate diagnoses or assessments.

We will introduce the various effects of rigid-body motion on a classical spin system in the presence of spatially-encoding magnetic field gradients. By accurately measuring motion with an optical tracking system and applying real-time corrections during the MR scan, many of these unwanted motion effects can be eliminated, resulting in images that are essentially free of motion artifacts. Furthermore, we will discuss potential applications of motion correction techniques to the detection (editing) of weak spectroscopic signals in a coupled quantum-mechanical system.

(This colloquium is intended to be accessible to UH physicists in all sub-fields)
