Source imaging with magnetoencephalography (MEG) provides good spatial accuracy for shallow sources and has been successfully applied for the study of brain cognition and the diagnosis of brain diseases. Yet, its utility for locating deep sources is unclear and remains a technical challenge. In this study, we proposed a new source imaging method for the assessment of brain activity in deep locations. A MEG sensor array with 306 channels was represented as a low-rank matrix plus sparse noise. The low-rank matrix was then used to estimate the source model with minimum variance beamforming. Simulations of a realistic head model indicated that the proposed method was effective. Our method was further verified in 10 patients with temporal lobe epilepsy, wherein the imaging results were consistent with clinical findings. (C) 2018 Published by Elsevier Ltd.
