This paper is a report of an investigation of the relationship between the condition number of a leadfield matrix of magnetoencephalography and source reconstruction accuracy. We suggest the use of the condition number as a promising a priori accuracy estimator of a neuromagnetic inverse problem (NIP) since various simulation studies demonstrated that the reconstructed source distribution has the...
In this paper, we investigate relationship between the condition number of a leadfield matrix of magnetoencephalography (MEG) and source reconstruction accuracy. We found from simulation studies that if the leadfield matrix has the higher condition number, reconstructed source distribution has the wider region and contains the more spurious sources
