Improved parallel MR imaging using a coefficient penalized regularization for GRAPPA reconstruction
Magnetic Resonance in Medicine, 06/08/2012
Liu W et al. – The imaging data from both phantom testing and in vivo MRI experiments demonstrate that the coefficient penalized regularization method in GRAPPA reconstruction is able to reduce noise amplification to a greater degree. Therefore, the method enhances the quality of images significantly when compared to the previous least squares and Tikhonov regularization methods.
