Figure 2. The drawing shows the reconstruction procedure for parallel PROPELLER-EPI, in which PROPELLER reconstruction was applied following parallel reconstruction. On the left, one blade of data was acquired by single-shot EPI (thick solid lines) with phase-encoding skipped (dashed lines, threefold acceleration in this example). After parallel imaging unfolding was performed, the missing data were filled (middle, thin solid lines). Subsequently, all of the blades were combined to fill the entire circular k-space using the PROPELLER reconstruction procedure (right).
