1. A method for generating a magnetic resonance perfusion image, comprising the steps of: from a perfusion series of magnetic resonance images comprising a plurality of tag images and at least one control image, pairing said tag images and said at least one control image to produce a plurality of pairs and generating, from each pair, an initially processed magnetic resonance perfusion image; subjecting each initially processed image to a quality control review by analyzing each initially processed image with respect to at least one image quality criterion, and rejecting any of said initially processed images that do not satisfy said quality criterion, thereby obtaining a plurality of acceptable magnetic resonance perfusion images; and automatically combining only said acceptable magnetic resonance perfusion images to obtain, as an output, a resultant magnetic resonance perfusion image.
