Parallel Magnetic Resonance Imaging Reconstruction by Image Editing

A new method is introduced here for parallel magnetic resonance imaging reconstruction that is based on the concept of two-step spectral editing in magnetic resonance spectroscopy (MRS). It uses a unitary 22 Fourier matrix (1 1;1 -1) for encoding and decoding. Although image editing is performed in the image domain, it does not suffer from the deficiency associated with SENSE when the prescribed field of view in phase-encoding direction is smaller than the region occupied by the object. Instead, the appearance of the aliasing in the reconstructed image is exactly the same as in the unaccelerated image.
