Abstract:
A method for producing an image of a subject with a magnetic resonance imaging (MRI) system, the steps comprising:a) acquiring a plurality of image data sets with the MRI system using a corresponding plurality of coils disposed adjacent the subject; b) reconstructing from the acquired image data sets a corresponding plurality of high resolution images; c) reconstructing from the acquired image data sets a corresponding plurality of low resolution images; d) calculating a coil dependent static phase term from the low resolution images; e) correcting the low resolution images for the static phase error to eliminate a coil dependent phase term; f) combining the corrected low resolution images; g) calculating from the combined corrected low resolution images resonance offset phase corrections; h) calculating a second static phase error for the high resolution images; i) correcting the high resolution images for the static phase error and correcting the high resolution images using the calculated resonance offset phase corrections calculated in step (g); j) combining the corrected high resolution images to produce the image of the subject.
