Abstract:
A method for combining an UNFOLD technique with a parallel MR imaging to obtain an MR image of an object, the method comprising:a) obtaining first k-space information about the object at a first time point and a first set of k-space locations; b) obtaining second k-space information about the object at a second time point and a second set of k-space locations, wherein at least one of the k-space locations in said second set is not contained in said first set; c) decomposing time variations of data associated with the first and second k-space information into a corresponding frequency content; d) for a first frequency of the frequency content, performing first parallel imaging to separate aliased and the non-aliased components that are overlapped; and e) for a second frequency of the frequency content, performing second parallel imaging to separate the aliased and non-aliased components that are overlapped, the second parallel imaging being different from the first parallel imaging.
