Abstract
An NMR method for producing a sequence of images throughout the cardiac cycle is disclosed. A fast scan NMR pulse sequence is continuously and asynchronously applied during successive cardiac cycles, and a phase encoding magnetic field gradient is incremented between cardiac cycles to acquire NMR data which is reconstructed using a 2DFT technique. The phase encoding magnetic field gradient is stepped in subincrements, and the odd and even phase encoding views are acquired in separate segments of the procedure in order to eliminate image distortion due to disturbance of the residual transverse magnetization.
