Volunteer datasets were reconstructed using both the proposed method and that from [8], with acceleration factors of 3.5 (skip factor of 4 in k-space) and 6.3 (skip factor of 8). We included sensitivity information into the encoding matrix for our implementation of the retrospectively-gated accelerated method from [8], and as a consequence both compared methods employed parallel imaging. While no significant differences were observed in terms of image quality, the present algorithm had a processing time several-fold shorter. Using a Matlab implementation for both methods, reconstruction time using the proposed approach was about 8 times faster.
