Method and system of MR imaging with reduced radial ripple artifacts

摘要

A method and system of MR imaging is disclosed that enables PROPELLER imaging to be feasibly carried out independently of slice orientation or anatomy of interest. The invention is directed to the acquisition of blades of MR data that are rotated about a central region of k-space and reconstructing an image of arbitrary slice orientation from the blades of MR data that is substantially absent of radial ripple artifacts caused by phase aliasing from tissue outside the field of view in the slice plane.
