Abstract
Electrical impedance tomography (EIT) is a non-ionizing imaging modality suitable for bedside pulmonary imaging. Currently, lung imaging with EIT in the ICU is tomographic due to the need for real-time images. However, linearized reconstruction methods have the potential to provide 3-D images in real time at the bedside. In this paper, the 3-D implementation of Calderón’s method provided in Shin and Mueller (Inverse Probl 36:124005, 2020) is further developed for a patient-specific domain. Results of reconstructions from simulated data of two realistic human torsos using the Calderón-based method and one step of an iterative Gauss-Newton method are made for four different electrode configurations. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2023.
