At least a portion of a body () is placed in a main magnetic field Bo within the examination volume of a MR device. The portion of the body () is subject to an imaging sequence including one or more RF pulses and switched magnetic field gradients to acquire imaging signals. The portion of the body () is subject to a navigator sequence applied at least once before, during, or after the imaging sequence. The navigator sequence includes one or more RF pulses and switched magnetic field gradients controlled to acquire navigator signals with a single-point or multi-point Dixon technique. Translation and/or rotation and/or shear data reflecting motion of the body are derived from the navigator signals during the acquisition of the imaging signals. The translation and/or rotation and/or shear data are used for adapting the imaging sequence and/or for motion correction during reconstruction of an MR image.
