Beyond the Medical X-ray, Non-ionizing Electrostatic Transconduction and its Biomedical Applications [Slides]

NESL Technical Report #: 2009-7-2


Abstract: Abstract
The use of high-energy X-rays for medical imaging is so well established that it is known even by the typical pedestrian. However, X-ray imaging has a number of draw backs including a lack of functional imaging, an inability to image soft tissue without toxic contrast materials, and the inherent hazards in exposure to ionizing radiation. In interventional cardiology, X-ray images merely provide a rough outline of the heart and clinicians must rely on intuition and the tactile response of their probes for guidance. In this talk we present early research on the use of electrostatic transconduction -- the use of near-field longitudinal dielectric waves -- for digital communication and sensing purposes and discuss its potential in displacing X-ray imaging in cardiac ablation procedures. This talk will be jointly presented by Dorothea Hall, MD, of the UCLA Medical Center and Jonathan Friedman, MSEE, of NESL/CENS.

Jonathan Friedman is a Ph.D. Candidate in Electrical Engineering in the Networked Embedded Systems Laboratory (NESL) and the Center for Embedded Networked Sensing (CENS) at the University of California, Los Angeles (UCLA). Jonathan attended the Georgia Institute of Technology (Georgia Tech) for his undergraduate education where he received a B.S. degree in Computer Engineering with an emphasis on embedded and mixed signal design. His M.S. degree is from UCLA in Electrical Engineering with a thesis entitled: "IRIS: The Design of a Ultra-low Power Infrared Communications and Obstacle Avoidance Array for Fleets of Mobile Sensor Nodes Operating in Dynamic Environments." Jonathan previously served as the Assistant Director of IT for an IMAX (large-format movie theaters) subsidiary, has founded three startup companies, won four design awards, sent over one-hundred product designs into commercial production, and holds two patents. His current research interests lie in sensor-systems design for salt-water and biomedical applications.

Dorothea Hall, M.D. is a Clinical Instructor in the Department of Anesthesiology at the David Geffen School of Medicine at UCLA. She attended medical school at the Medical College of Wisconsin, Milwaukee (MCW) where she also did her residency. She recently completed a fellowship in cardiothoracic anesthesia and is board certified in transesophageal echocardiography (heart ultrasounds taken though the esophagus). She authored a case presentation for the 2007 American Society of Anesthesiology (ASA) General Meeting. Her research interests include perioperative radiation safety, cardiovascular anesthesia, and cardiac catheterization procedures. She is currently responsible for the training of anesthesia residents at the UCLA Medical Center.
