The published paper "Sparse sensor layout design via recursive orthogonalization of the forward solution matrix with a realistic noise environment in MEG" presents a new method for optimizing the configuration of sensor arrays for MEG. The method is based on recursive orthogonalization of the direct solution matrix and allows forming multi-sensor systems with the maximum signal-to-noise ratio. The approach is highly computationally efficient: it requires 50-70 times less resources than existing methods. Experiments show that within a given region of interest, the proposed algorithm provides an SNR level comparable to industry standards, such as the Elekta Neuromag MEG system.
