<p num="1"><br/><br/><br/>The invention relates to a method for interpreting the current distribution of <br/>an object being measured using basis vector components calculated from the <br/>measured signals. The components in question have been so selected that they <br/>describe the features, as independent as possible, of the current distribution <br/>being examined, which enhances the computation and makes it more accurate. <br/>This is achieved by converting the measured signals into a more natural form <br/>from the standpoint of the current distribution while totally eliminating the <br/>signals associated with the external interferences. A conversion of this kind <br/>has been described e.g. in patent publication F120030392. After the <br/>conversion, the source modelling is performed in an optimal manner using the <br/>basis vector components of the signal space instead of the actual measurement <br/>signals. One substantial feature of the invention is that after the <br/>conversion, the source model need not be regularised any more.<br/>
