Abstract:
Systems methods, and other embodiments associated with acquiring intersecting TrueFISP images using grouped reverse centric phase encoding are described. One example method includes controlling an MRI apparatus to produce a TrueFISP sequence that delays acquisition of the center of k-space to reduce saturation banding artifacts. The example method also includes controlling the MRI apparatus to produce a TrueFISP sequence that reduces eddy current artifacts by grouping (e.g., pairing) lines in k-space. The method concludes by acquiring NMR signal in response to the TrueFISP sequence.
