MR image reconstruction exploiting nonlinear transforms has successfully been implemented using projections onto principal components in a high-dimensional kernel feature space, employing kernel PCA. Image quality was found to improve considerably relative to standard CS reconstruction with wavelet and finite-differences transforms.
