ABSTRACT:
Apparatus and method for nuclear magnetic resonance (NMR) testing an object includes subjecting the object to a magnetic field, the field comprising a gradient component (G.sub.read) for encoding spatial information about the object, applying excitation pulses (R.F.) at selected intervals to excite nuclear magnetic resonance, at least two of the intervals and the encoding gradient component during those intervals being selected such that, for such intervals, the values of the integral of the gradient component with respect to the interval duration are proportioned according to consecutive powers of an integer, I, greater than two, and detecting the resonance response signals.
