SPN: A magnetic resonance diagnostic device is intended for general diagnostic use to present images which reflect the spatial distribution and/or magnetic resonance spectra which reflect frequency and distribution of nuclei exhibiting nuclear magnetic resonance. Other physical parameters derived from the images and/or spectra may also be produced. The device includes hydrogen-1 (proton) imaging, sodium-23 imaging, hydrogen-1 spectroscopy, phosphorus-31 spectroscopy, and chemical shift imaging (preserving simultaneous frequency and spatial information).,UMD: Scanning systems that use strong magnetic fields, radio-frequency (RF) radiation, and computerized processes to translate hydrogen nuclei distribution (some systems can translate other nuclei exhibiting nuclear magnetic resonance) in body tissue into images of anatomic structures. Following exposure to high magnetic and RF fields, body-tissue nuclei emit low-power RF signals that are detected by the system RF receiver. The computer uses these RF data to c
