Abstract: Methods for operating a magnetic resonance apparatus and systems therefrom are provided. A method includes generating, via a coil former surrounding a subject or object of interest and disposed in the magnetic resonance apparatus, a plurality of field modes external to the subject or object, measuring for each of the plurality of external field modes, an associated internal field produced within the subject or object, generating, via the coil former a combination of external modes to produce a target internal field in the subject or object, and measuring nuclear magnetic resonance signals due to the resulting field from the combination to acquire an image or spectrum of the subject or object.

Abstract: A visible and/or MRI visualizable permanent image is formed in a gel in a container which maintains the gel a dimensionally stable shape, which gel contains uniformly dispersed therein in storage stable form at last one radiant energy, e.g., ionizing radiation, polymerizable monomer in a concentration effective to form an insoluble polymer in the gel which alters the relaxation time of the solvent in any area thereof in which the polymer is formed, e.g.
