完整电极模型下电阻抗断层扫描二维均匀圆盘上电势分布的解析解通过无限线性方程组表示。对于具有两个电极的分流电极模型,我们的解与先前通过椭圆积分表示的解一致。狄利克雷到诺伊曼图是通过非线性最小二乘导出用于统计估计的。该解决方案在体模实验中得到验证,并应用于体内乳房接触阻抗估计。统计假设检验用于测试电极之间的接触阻抗是否相同或全部为零。我们的解决方案对于临床环境中不良表面接触的快速实时测试特别有用。
An analytic solution of the potential distribution on a 2D homogeneous disk for electrical impedance tomography under the complete electrode model is expressed via an infinite system of linear equations. For the shunt electrode model with two electrodes, our solution coincides with the previously derived solution expressed via elliptic integral. The Dirichlet-to-Neumann map is derived for statistical estimation via nonlinear least squares. The solution is validated in phantom experiments and applied for breast contact impedance estimation in vivo. Statistical hypothesis testing is used to test whether the contact impedances are the same across electrodes or all equal zero. Our solution can be especially useful for a rapid real-time test for bad surface contact in clinical setting.
