<p>NMR data required to reconstruct an image is divided into central k-space views (313) and peripheral k-space views (315). 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 (322) and a second gating signal is produced when respiration is within a wider acquisition window (324). Central k-space views (313) are acquired when the first gating signal is produced and peripheral k-space views (315) are acquired when the second gating signal is produced. <IMAGE></p> |
