ABSTRACT: Method of and device for determining a nuclear spin den- sity distribution in a part of a body. It has been found that devices for determining nuclear spin density distributions in an object by means of nuclear spin resonance measurements produce artefacts in the calculated density distributions. The artefacts occurring are dependent on the gradient magnetic fields which are used during the measurements and which in- fluence the excited nuclear spin. The invention concerns two filters for elimination of the artefacts in depen- dence on the kind of modulation of the gradient magnetic field.
