Electrical Impedance Tomography Reconstruction with Partial Boundary Measurements

Electrical Impedance Tomography (EIT) is a non-invasive imaging technique that enables real-time monitoring of human organ function by reconstructing the internal conductivity distribution. In clinical settings, electrode placement is often constrained, resulting in incomplete boundary measurements and a consequent severe degradation of image reconstruction quality. In this work, we investigate EIT reconstruction under partially covered electrode boundaries using our recently proposed nonlinear weighted anisotropic total variation (NWATV) regularizer. Through numerical simulations and water tank experiments with three-quarter and half-circumferential electrode configurations, we demonstrate that NWATV significantly improves both structural fidelity and robustness in reconstructed images under partial electrode coverage. Our findings indicate that NWATV holds potential for clinical use in limited-electrode configurations.
