fMRI denoising for high-resolution brain functional analysis

We developed and applied semi-supervised dictionary learning method to effectively increase the signal-to-noise Ratio (SNR) of the functional Magnetic Resonance Imaging (fMRI) signals. The denoising process is the foundation for later high-resolution brain functional analysis, including pin-pointing the functional localization results (as shown in the figure) and more clear brain network maps.
