Magnetic Field Gradient Calibration as an Experiment to Illustrate Magnetic Resonance Imaging
Seedhouse, Steven J.; Hoffmann, Markus M.
Journal of Chemical Education, v85 n6 p836-838 Jun 2008
A nuclear magnetic resonance (NMR) spectroscopy experiment for the undergraduate physical chemistry laboratory is described that encompasses both qualitative and quantitative pedagogical goals. Qualitatively, the experiment illustrates how images are obtained in magnetic resonance imaging (MRI). Quantitatively, students experience the relationships between gradient strength, spectral width, and the quality of the obtained projection images as they calibrate the maximum field gradient strength of the instrument. They also find out the size of a trapped air bubble in their sample in close analogy how one could obtain information on physical sizes of objects in MRI. (Contains 1 table and 3 figures.)
