Claim One:
1. An MR method for the imaging of an at least partly moving object (H) in an examination zone, wherein the nuclear magnetization is excited during an examination in the presence of a steady magnetic field by sequences (SI), which include at least a respective RF pulse (RF) of defined frequency, a number of MR signals received with a defined phase position and produced under the influence of additional magnetic gradient fields is evaluated, a motion parameter of the object is continuously measured for motion compensation and the parameters of the sequence are varied in dependence on the measurement, characterized in that the following steps are taken: measuring the variation in time of n correlated motion parameters (d, d 1, d 2 ) during a preparation phase preceding the MR examination, measuring m of such n motion parameters (d) during the MR examination, deriving the motion parameters (d 1, d 2 ) that have not been measured during the MR examination from the measured motion parameters, varying the parameters of the sequence in dependence on the calculated or measured motion parameters in order to achieve motion compensation.
