Abstract
A method of magnetic resonance imaging includes subjecting a region of a patient being imaged to magnetic resonance imaging pulse sequences thereby generating magnetic resonance echoes emanating from the region. The echoes are encoded with magnetic gradients and collected as k-space data in separate consecutive acquisitions. Each acquisition successively fills in one of a number of distinct subsets of k-space based on the encoding of the collected echoes for that acquisition. In turn, a reconstruction algorithm is applied to the k-space data after each acquisition to generate a series of temporally updated image representations of the region. Further, a magnetic resonance imaging apparatus for performing the method is also provided.
