PROBLEM TO BE SOLVED: To obtain an absolute value of a suitable electrical characteristic value according to living-body features such as a sex, age and somatotype.SOLUTION: This measuring device includes a mathematical model preparing means 34 which prepares a mathematical model of three or more dimensions by making the electrical characteristic value of each mesh change into a plurality (n) and be operable, a mathematical model modifying means 44 which selects a tomographic model corresponding to desired living-body feature parameters from a tomographic model database 41 wherein a plurality of kinds of standard tomographic models different in the living-body feature parameters in a plurality are accumulated, and which modifies the tomographic model and supplies it to the mathematical model preparing means 34 to prepare the mathematical model, and an input pair electrode and an output pair electrode. Based on first potential differences (Dmodel) in a plurality (n) generated respectively in the output pair electrode and on a second potential difference (Dmean) generated in the output pair electrode, which is obtained by actual measurement, an optimum electrical characteristic value in each pixel is estimated and determined, and based on this, a tomographic image is displayed.COPYRIGHT: (C)2012,JPO&INPIT【課題】性別と年齢と体型等の生体的特徴に応じて適切な電気的特性値の絶対値を得る。【解決手段】各メッシュの電気的特性値を複数(n)に変化させて演算可能な3次元以上の数学モデルを作成する数学モデル作成手段34と、複数の生体特徴パラメータが異なる標準断層モデルが複数種類蓄積された断層モデルデータベース41から所望の生体特徴パラメータに対応する断層モデルを選択し、断層モデルに変更を施し、前記数学モデル作成手段34に供給して数学モデルを作成させる数学モデル変更手段44と、入力ペア電極と出力ペア電極とを具備し、数学モデルを用いて算出した、前記出力ペア電極にそれぞれ発生する複数(n)の第一の電位差(Dmodel)と、実測により得られた前記出力ペア電極に発生する第二の電位差(Dmean)と、に基づき、各画素における最適な電気的特性値を推定し決定し、これに基づき断層画像を表示する。【選択図】図1
