Abstract
A method for combining UNFOLD with a parallel magnetic resonance imaging (MRI) technique, such as SMASH, SENSE, or SPACE-RIP is provided. When acquiring only one nth of the usual amount of k-space data, data is acquired n times faster, but n signals will overlap in the resulting images. By spreading the n signals over all of the available temporal frequency bandwidth, UNFOLD reduces the amount of overlap to n/2. A parallel imaging method with an acceleration n/2 can finish the reconstruction by separating the n/2 overlapped signals. The result is a time series of non-corrupted images that are acquired n times faster than normal.
