Patent ID: 7865227

Claim:
A method for producing an image of a subject positioned in a field of view (FOV) of a magnetic resonance imaging (MRI) system, the steps comprising: a) acquiring with the MRI system a set of projection views at each of a plurality of cardiac phases and during each of a plurality of heartbeats; b) producing a composite image for each cardiac phase with projection views acquired during the corresponding cardiac phase for a plurality of heartbeats, each composite image depicting the subject at the corresponding cardiac phase; c) reconstructing an image of the subject at a selected cardiac phase by: c)i) backprojecting a set of projection views acquired at the selected cardiac phase into the FOV and weighting the value backprojected into each image pixel by the value of the corresponding pixel in the composite image that depicts the subject during the selected cardiac phase; and c)ii) summing the backprojected values for each image pixel.
