A Noncausal IIR FB approach to PMR image reconstruction

Magnetic Resonance Imaging (MRI) is one of the most important imaging modalities for clinical diagnoses and medical research. Parallel Magnetic Resonance Imaging (pMRI) as a newly developed MRI technique has the advantage of accelerated imaging speed. However, the current image reconstruction methods for pMRI suffer visible artifacts and noise effects. To further enhance pMR image reconstruction, this paper proposes a new reconstruction method based on the noncausal infinite impulse response (IIR) filter bank (FB) model. The experimental studies show that the proposed method can produce more accurate image than the conventional method.
