MRI USING SPATIALLY ADAPTIVE REGULARIZATION FOR IMAGE RECONSTRUCTION

摘要

A magnetic resonance (MR) imaging system may include at least one controller which may acquire echo information of a region of interest (ROI) the echo information may include first image information suitable for reconstructing at least part of a first image at a selected contrast; obtain previously reconstructed image information of one or more previously reconstructed images having a contrast different than the selected contrast; extract information from the previously reconstructed image information; determine spatially adaptive regularization weights for regularized reconstruction based upon the extracted information; and/or reconstruct the first image information in accordance with the spatially adaptive regularization weights and the echo information.
