abstract

We use body surface electrical current stimulation and measurements to generate images of the internal electrical properties. This principle is used in geophysics, process monitoring, and medical imaging. Currently, the most successful medical application of electrical impedance tomography (EIT) is for imaging the thorax, where the movement on conductivity contrasting air and blood can be imaged over time. The generation of EIT images requires solving an inverse problem, which is ill-conditioned because of the diffuse nature of current propagation. The technology is thus sensitive to electrode properties, data quality, and patient movement.

To address these issues, several innovative strategies to analyze and interpret these data have been developed. This talk will explain our recent progress in imaging the chest with EIT, and the image generation and interpretation strategies that are required.

biography

Andy Adler is professor and Canada Research Chair (Tier II) in biomedical engineering in Systems and Computer Engineering at Carleton University in Ottawa, Canada. His research interests broadly in the area of biomedical measurement and robust data analysis. He is author of ten book chapters, four patents, eighty eight journal and 190 conference papers. Previously, he taught and researched at the University of Ottawa, and worked in senior technology positions at BioDentity (now cryptometrics), AiT (now 3M), DEW Engineering (now ActivCard), and CIL explosives (now Orica). Andy Adler received the B.A.Sc. (honours) in Engineering Physics from the University of British Columbia in 1990, and a Ph.D. in Biomedical Engineering from the École Polytechnique de Montréal in 1995. He also worked at postdoctoral positions at McGill University and the University of Colorado Health Sciences Center.
