Abstract
NMR data required to reconstruct an image is divided into central k-space views and peripheral k-space views. NMR navigator signals are acquired during a scan to indicate patient respiration and a first gating signal is produced when respiration is within a narrow acquisition window and a second gating signal is produced when respiration is within a wider acquisition window. Central k-space views are acquired when the first gating signal is produced and peripheral k-space views are acquired when the second gating signal is produced.
