  • Publication number: 20240201303
    Abstract: In a method of estimating motion of an object and/or magnetic field offsets in a region surrounding the object during a magnetic resonance (MR) imaging scan of the object, superimposed magnetic fields and radiofrequency fields are generated according to an MR sequence for forming images, the MR sequence comprising a train of sequence modules, each sequence module comprising a radiofrequency (RF) excitation segment and an image encoding gradient segment, the MR sequence further comprising a plurality of navigator gradient segments. The navigator signal is acquired along a trajectory in k-space and expressed as a discrete time series comprising a predefined number of complex-valued signal datapoints. The navigator signal acquired in a first sequence module is used to calculate a transformation matrix which relates rotation angles and translational shifts and/or changes of the magnetic field to corresponding changes in navigator signal in a first order approximation.
