Paper Abstract

A progressive reconstruction technique is presented in magnetic resonance (MR) imaging. To do so, matching pursuit algorithm is applied to MR Imaging. For MR imaging, Fourier basis set is used as a dictionary of MP algorithm. In the progressive reconstruction algorithm proposed in this paper, the inner products of object signal and basis functions are utilized instead of those of residual signals and basis functions for original matching pursuit algorithm. By reconstructing the object hierarchically, one can achieve a quick recognition of image during data acquisition, i.e., at each phase encoding step, the image is reconstructed and updated progressively while, in conventional, image reconstruction is performed after all phase encoding steps. To verify the proposed technique, computer simulations and experiments with whole body MRI system are performed.
