Limitations and challenges of EIT-based monitoring of stroke volume and pulmonary artery pressure. [PDF]
, 2018 Electrical impedance tomography (EIT) shows potential for radiation-free and noninvasive hemodynamic monitoring. However, many factors degrade the accuracy and repeatability of these measurements. Our goal is to estimate the impact of this variability on
