As near-infrared spectroscopy (NIRS) broadens its application area to different age and disease groups, motion artifacts in the NIRS signal due to subject movement is becoming an important challenge. Motion artifacts generally produce signal fluctuations that are larger than physiological NIRS signals, thus it is crucial to correct for them before obtaining an estimate of stimulus evoked hemody...

Compressed sensing (CS) has been demonstrated to accelerate MRI acquisitions by reconstructing sparse images of good quality from highly undersampled data. Motion during MR scans can cause inconsistencies in k-space data, resulting in strong motion artifacts in the reconstructed images. For CS to be useful in these applications, motion correction techniques need to be combined with the undersam...

INTRODUCTION Functional Magnetic Resonance Imaging (fMRI) is being used extensively in neuroscientific studies and is entering the clinical field. Due to its low inherent effect to noise ratio even at high field strength the results are often compromised by adverse events during the acquisition. The most frequent cause of signal fluctuations that degrade the detection of paradigm induced neuron...
