Imaging with Electricity
Electrical Impedance Tomography (EIT) applies low-amplitude currents and uses the measurements to reconstruct images of the conductivity distribution within the body. EIT has low spatial resolution, it is non-invasive and minimally-cumbersome and is thus useful for enhanced physiological monitoring. This talk will review the physics of EIT and image reconstruction, with an emphasis on making calculations robust to electrode-contact errors. We will then review the main current applications (optimization of ventilator settings) as well as potential outpatient applications. Finally, we'll look at lifestyle and stress-monitoring technology and metrics.
Bio
Adler is a Canada Research Professor in biomedical engineering in Systems and Computer Engineering at Carleton University. A main focus of Adler’s work is electrical impedance tomography (EIT), the imaging of the body using small applied electrical currents. He has worked closely with industry to translate the technology to the bedside. He is the maintainer of EIDORS.org - an open-source software for EIT, and has led international consensus projects on EIT image reconstruction, terminology and clinical applications.
