Recent Advances in Acquisition/Reconstruction Algorithms for Undersampled Magnetic Resonance Imaging

Giuseppe Placidi
2014 Journal of Biomedical Engineering and Medical Imaging

Non-Iterative Regularized reconstruction Algorithm for Non-CartesiAn MRI: NIRVANA

Satyananda Kashyap, Zhili Yang, Mathews Jacob
2011 Magnetic Resonance Imaging  
We introduce a novel non-iterative algorithm for the fast and accurate reconstruction of non-uniformly sampled MRI data.  ...  The proposed scheme derives the reconstructed image as the non-uniform inverse Fourier transform of a compensated dataset.  ...  For example, a typical functional MRI dataset has around 1000 images. The reconstruction of each of these images using CG will require several hours.  ...

Imry Kissos, Michael Levit, Arie Feuer, Aharon Blank
2013 Journal of magnetic resonance (San Diego, Calif. 1997 : Print)
