Claim One:
1. A method of obtaining magnetic resonance imaging signals comprising the steps of a) placing an object to be imaged in a magnetic field (B.sub.0), b) applying a plurality of RF excitation pulses to said object to selectively excite nuclei in a slice through said object, one pulse of said plurality of RF excitation pulses serving as a template for other RF excitation pulses with said plurality of RF excitation pulses having varying tip-angle profiles for said nuclei whereby a stabilized signal profile is realized and wherein a tip-angle profile for the last pulse in the plurality of RF pulses is given, the required sequence of tip-angles to achieve a given signal level for all possible signal levels is known, and the tip-angle profiles .theta..sub.i-1 (x) for pulse i-1 are recursively determined from a known tip-angle profile .theta..sub.i (x) for pulse i, beginning with the last tip-angle profile, and c) detecting said signals from said nuclei.
