Computer image reconstruction of bioelectric currents from magneto-acoustic measurements

Abstract

The problem of image reconstruction of multiple bioelectric dipolar current sources is considered. The authors report a novel image reconstruction method which is capable of finding not only the magnitude but also the orientation of dipoles for simple dipole combinations. The input simulated data is provided by a magnetoacoustic technique of noninvasive current measurement. The reconstruction method, called the vectorized iterative least-squares technique (V-ILST), is based on the classical ILST approach used in computerized tomography.<>
