Method and the device which use the multichannel measurement signal in the source modeling

摘要

This invention regards the method of elucidating the current distribution of measuring object ones making use of the basis vector component which was calculated from the signal which was measured. The investigation object component is selected as described the feature of the current distribution which is investigated as independently as possible. Because of this, operation improves, also operational precision rises. As for this, interference and relation from outside while losing the signal which is attached completely, it is achieved the signal where these were measured, by converting to more natural form from viewpoint of current distribution. Concerning the conversion of this kind, there is statement in patent release FI20030392. After the converting, the source modeling is done optimumly in place of the actual measurement signal making use of the basis vector component of the signal space. Substantial one feature of this invention after the converting, is already not to be necessary to convert the source model correctly. Selective figure Figure 1
