PROBLEM TO BE SOLVED: To measure electrical characteristic such as electrical conductivity including anisotropy with good precision with an electrical characteristic measuring apparatus using nuclear magnetic resonance.SOLUTION: When an electrical characteristic of a predetermined region of a subject placed in a static magnetic field space is measured by using nuclear magnetic resonance signals measured from the region, measurement data measured by coinciding direction of a tissue structure of the subject with the direction of the static magnetic field, and measurement data measured with crossing the direction of the static magnetic field are used as measurement data. A rotating magnetic field map of the region is created from the measurement data, and the electrical characteristic is calculated by using the rotating magnetic field map. The electrical characteristic including anisotropy is calculated by using information about the direction of tissue structure.SELECTED DRAWING: Figure 5【課題】核磁気共鳴を利用した電気特性測定装置において、異方性を含む導電率等の電気特性を精度よく測定する。【解決手段】静磁場空間に配置された被検体の所定の領域から計測した核磁気共鳴信号を用いて、当該領域の電気特性を測定する際に、計測データとして、静磁場の方向に対し、前記被検体の組織構造の方向を一致させて計測した計測データと、静磁場方向に対し交差させて計測した計測データを用いる。計測データから前記領域の回転磁界マップを作成し、当該回転磁界マップを用いて電気特性を算出し、その際、組織構造の方向に関する情報を用いて、異方性を含む前記電気特性を算出する。【選択図】図５
