title: Whole-body nuclear magnetic resonance scanning: n.m.r. studies of tumour cells.
abstract: A technique, field-foxusing nuclear magnetic resonance (n.m.r.) spectroscopy (FONAR), is described for doing n.m.r. scans in large samples. The method utilizes a shaped d.c. magnetic field that confines the n.m.r. signal-producing region of the sample to a small volume called the resonance aperture. The aperture contains the required values of the Ho field to fully bracket the band of the r.f. pulse. The magnet system and r.f. pick-up coil that achieved the first human n.m.r. scan are discussed.
