Abstract
The invention relates to an apparatus for the examination of an object by the application of methods, such as magnetic imaging, based on nuclear magnetic resonance. The apparatus includes means for creating a first magnetic field over an object to be examined as well as means for creating and registering a nuclear magnetic resonance signal. The apparatus further includes means for creating a second magnetic field in a manner that the formation of nuclear magnetization occurring between successive excitation and signal pick-up events is at least partially effected while the second magnetic field is switched on.
