Abstract
Temporal resolution in dynamic magnetic resonance imaging is obtained by establishing a representation of static material in the field of view by averaging all signal acquisitions for a full field of view, and Fourier transforming the averaged data to yield an averaged image. The known dynamic portion of the image is set to zero to yield an image restricted to the static portion of the image. The averaged static portion is then inverse transformed to generate a synthetic MR raw data set that is an estimate of the data that would be collected if the object consisted only of the static material. The synthetic data are subtracted from the MR data for each view to eliminate the data for static material. The resulting data then represents the dynamic material which can be individually reconstructed.
