摘要
A method for producing an NMR image depicting the heart of a subject at a selected cardiac phase, the steps comprising: (a) producing a signal indicative of successive cycles of the subject's heart; (b) acquiring NMR data views throughout each of said successive cycles, each NMR data view being associated with a time stamp which indicates when the view was acquired within one of said heart cycles; (c) forming an array of NMR data from which an image depicting the heart at the selected cardiac phase can be reconstructed by: (i) correlating the selected cardiac phase with a desired point in either a systolic period or a diastolic period of an average heart cycle; (ii) selecting acquired NMR data which correlates with the desired point in either the systolic period or diastolic period of the heart cycle in which the NMR data was acquired; and (d) reconstructing an image from the array of NMR data formed from the selected acquired NMR data.
