Title: Magnetic resonance projection imaging of dynamic subjects

Abstract: An MRI system performs a cardiac gated scan of a moving coronary artery using preparatory pulse sequences and two-dimensional EPI (echo planar imaging) pulse sequences. The preparatory pulse sequence saturates spin magnetization in regions surrounding a slice which contains the coronary artery at one point in time during each cardiac cycle. The EPI imaging pulse sequence is performed later in the cardiac cycle after the coronary artery has moved and a two-dimensional image is reconstructed by projecting NMR signals from a volume within which the coronary artery moves during the cardiac cycle.
