Abstract
Magnetic resonance images of the distribution of a substance within a sample are obtained by splaying a pair of magnetic field generating coils relative to each other to generate a magnetic field gradient along an axis of the sample. In other aspects, electron spin resonance data is derived from animal tissue, or images are derived from a sample that includes dissipative material, using a radio frequency signal of sufficiently low frequency.
