Abstract

A method for operating a nuclear magnetic resonance apparatus having coils for generating a fundamental magnetic field and gradient magnetic fields in which an examination subject is disposed, and having a transmitter/receiver for generating a sequence of high-frequency pulses and for acquiring nuclear magnetic resonance signals from the examination subject operates the apparatus by simply switching the gradient fields, leaving the gradient fields unmodulated. The pulse sequences generated by the pulse generator and by the gradient field coils are such that a dynamic equilibrium magnetization is generated. The method is particularly suitable for rapid generation of a tomographic image.
