Claim One:
1. A method of providing dynamic magnetic resonance imaging (MRI) of an object in an MRI system, comprising the steps of: a) applying a magnetic resonance excitation from the MRI system to the object; b) reading out magnetic resonance signal encoded in spatial frequency for a plurality of spatial regions with two or three spatial dimensions and a temporal dimension, wherein the read out is pseudo-randomly undersampled in the spatial frequency dimensions and the temporal dimension providing k-space data that is pseudo-randomly undersampled in the spatial frequency dimensions and the temporal dimension; c) using the readout data to create a sequential time series of spatial frequency data sets by generating interpolated data in the spatial frequency dimensions and the temporal dimension; d) using the sequential time series of spatial frequency data sets to create a temporal series of spatial images; e) measuring movement of each spatial region of the plurality of spatial regions and providing motion weighting to each spatial region of the plurality of spatial regions according to the measured movement; and f) using the motion weighting for each spatial region to create an image, wherein spatial regions with greater motion have lower weighting.
