Abstract
A method for producing a time-series of images of a subject with a magnetic resonance imaging (MRI) system is provided. The MRI system is used to acquire a time-series undersampled k-space data set, in which a selected number of k-space data subsets in the time-series data set includes both image data and calibration data. Moreover, the calibration data in each of these selected number of k-space data subsets includes a portion of a desired total amount of calibration data. For example, each of these selected number of k-space data subsets include calibration data that is acquired by sampling a different partition of a calibration data sampling pattern. A time-series of images of the subject is then produced by reconstructing images of the subject from the acquired time-series of undersampled k-space data sets. These images are substantially free of undersampling artifacts.
