| Abstract(in English) | To measure bioimpedance of a cross section in the local tissue, a divided electrode measurement method is proposed, where a current electrode is divided into many parts by slits. Layered tissues, including a tumor in some case, are represented by distributed circuits consisting of extra-cellular and intra-cellular resistances and membrane capacitances. These parameters are estimated from the impedance data measured noninvasively by using the divided electrode. The method is evaluated by computer simulations and experiments using circuit models. As a result, the parameter values have been estimated with a reasonable accracy. Impedance distributions are tryed to be represented by an image. |
