The D-bar algorithm based on Nachman's 2-D global uniqueness proof for the inverse conductivity problem (Nachman, 1996) is implemented on a chest-shaped domain. The scattering transform is computed on this chest-shaped domain using trigonometric and adjacent current patterns and the complete electrode model for the forward problem is computed with the finite element method in order to obtain simulated voltage measurements. The robustness and effectiveness of the method is demonstrated on a simulated chest with errors in input currents, output voltages, electrode placement, and domain modeling.
基于 Nachman 二维全局唯一性证明的 D-bar 算法（Nachman，1996）应用于一个胸部形状的域。散射变换在这个胸部形状的域上使用三角函数和相邻电流模式进行计算，正向问题的完整电极模型使用有限元方法进行计算，以获得模拟的电压测量值。该方法在具有输入电流、输出电压、电极位置和域建模误差的模拟胸部上的稳健性和有效性得到了证明。
