ABSTRACT:
Two-dimensional or three-dimensional, time-resolved MR frame images are acquired during a dynamic study of a subject. A composite MR image is produced and this is used to reconstruct each image frame by weighting the backprojection of each projection view acquired for that image frame. The composite image may be reconstructed from views acquired separately, or it may be produced by combining views acquired during the course of the dynamic study. A number of different clinical applications of the method are described.
