Matlab Toolbox for Undersampled MRI Reconstruction with Contourlet Transform This toolbox contains Matlab files that implement the sparse sampling and reconstructioin of MRI with contourlet transform described in paper: Xiaobo Qu, Weiru Zhang, Di Guo, Congbo Cai, Shuhui Cai, Zhong Chen. Iterative thresholding compressed sensing MRI based on contourlet transform, Inverse Problems in Science and Engineering, 18(6):737-758, 2010. You can download this toolbox at http://quxiaobo.8866.org/project/CS_MRI_Contourlet/CS_MRI_Contourlet.zip You can download the paper at the following links: http://www.informaworld.com/smpp/content~db=all~content=a925482588~frm=titlelink Or http://quxiaobo.8866.org/pdf/IST_Contorulet_CS_MRI_Xiaobo%20Qu_Inverse%20Problems%20in%20Science%20and%20Engineering.pdf %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% To use this toolbox, the following related toolbox is required: (1)Object Evaluation Toolbox for MRI reconstruction at http://quxiaobo.8866.org/project/CSMRI_Evaluation/CSMRI_Evaluation.zip (2)Rice wavelet toolbox at http://dsp.rice.edu/software/rice-wavelet-toolbox (3)Sharp frequcy localized contourlet(SFLCT) toolbox at http://lu.seas.harvard.edu/code/ContourletSD.zip (4)The fft2c.m and ifft2c.m are extracted from Dr.Michael Lustig's Sparse MRI toolbox at http://www.stanford.edu/~mlustig/sparseMRI_v0.2.tar.gz %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Acknowledgement We make our software routines available for non-profit scientific research, enabling others researchers to understand, reproduce and extend our work.
