1. Introduction
Electrical Impedance Tomography (EIT) shows promise for monitoring a patient's heart and lungs
through the movement of conductivity contrasting blood and air. We are interested in using EIT to
measure blood flow, which is useful for monitoring changes in cardiac output and ventilation / perfusion
matching in the lungs. The goal of this research is to determine the accuracy of EIT measurements of
blood flow in the heart and lungs.
2. Methodology
The data collection protocol was reviewed and approved by the institutional research ethics board. All
patients underwent electrocardiogram-gated contrast enhanced Cardiac Computed Tomography (CT)
scans at the University of Ottawa Heart Institute. Radio-opaque contrast agent (Omnipaque 350) was
