Portable nuclear magnetic resonance imaging system
Abstract
A portable nuclear magnetic resonance (NMR) imaging system has been designed for noninvasive investigations of immobile objects, e.g., living plants in their natural environment, a human finger or similar objects not exceeding a diameter of 12 mm. The NMR spectrometer is equipped with a permanent magnet, flat biplanar gradient coils, and a battery powered amplifier network with a phase-encoding unit, capable of imaging experiments on volumes of (1 cm)3 with a spatial resolution of 63 μm. The total weight of the instrument is approximately 90 kg. First applications of this system include spin-echo images of phantoms and living plants in a greenhouse.
