| Research Abstract |
Three-dimensional impedance CT using magnetic field was studied. From measurements using model, it was confirmed that using edge information of the object and controlling the phase of the eddy current make the two dimensional image more clear. By setting two assistant electrodes at both outsides of detecting electrode, more clear imaging was obtained in the direction of z-axis of the three-dimensional image,. It was found that a measurement from one side of subject, namely electro-magnet and electrodes are setting on the surface of the subject, would be able to estimate resistivity of the deep part.
