ABSTRACT:
Selective excitation is used to excite to resonance nuclear spins in a predetermined planar slice of a target. The received NMR signals are then used to correct non-homogenity of a static magnetic field based upon the calculated spin-spin relaxation time T.sub.2 * of the observed NMR signal.
