摘要
A method for a parallel image reconstruction is disclosed. The method includes (a) acquiring image information by channel via parallel coils in a magnetic resonance imaging (MRI) scanner; (b) extracting low-frequency signals from the image information; (c) reconstructing low-frequency images from the low-frequency signals; (d) generating filter banks by using the low-frequency images; and (f) reconstructing a final image by using the filter banks. The generating of the filter banks includes separately generating low-frequency image information for reconstruction of magnitude information and low-frequency image information for reconstruction of phase information, and then separately generating a filter for reconstruction of the magnitude information and a filter for reconstruction of the phase information.
