3D FRONSAC with PSF reconstruction.

Purpose: This study extends the Fast ROtary Nonlinear Spatial ACquisition (FRONSAC) method to include 3D acquisitions and reconstructions. It uses a transform domain reconstruction which is needed to make 3D reconstructions practical and provides new insights into how parallel imaging performance is enhanced by FRONSAC encoding.

Methods: This work developed the first examples of FRONSAC incorporated into a 3D acquisition.
