Abstract
Electrical Impedance Tomography (EIT) reconstruction can estimate thorax fluid content. Its use in critically ill patients is promising and may prove clinically useful. Boundary voltages (16-electrode frames) were obtained with our 50 kHz–5 mA IMPETOM system. Comparison of the 492-element Newton-Raphson algorithm with EIDORS open source tool (NOSER & GREIT algorithms), applied to a healthy volunteer, suggests that anatomically adjusted 3D models give better results. Nevertheless for phantom imaging an initial uniform image yields more accurate reconstructions. The results help in the selection and implementation of the reconstruction method for systems similar to IMPETOM.
