3dimensional electric impedance tomography using magnetic field

研究了基于磁场的三维阻抗CT。通过模型测量，证实了利用物体边缘信息和控制涡流相位可以使二维图像更加清晰。通过在检测电极的两侧设置两个辅助电极，可以在三维图像的z轴方向上获得更清晰的成像。我们发现，从物体的一侧测量，即在物体表面设置电磁铁和电极，可以估计出深部的电阻率。

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.
