Current Research Work

  • In medical imaging, I am developing new acquisition techniques for ultrasound with the goal of improving diagnostics. Two current research directions in this area are 3D ultrasound and spatial compounding to improve the visualization of anatomy and pathology.
  • In medical information systems, I am working with industry to improve the timely dissemination of digital medical images and associated data to health care providers. In particular I am currently working on new methods for radiologists to navigate large image sets. This is in response to the growing size of studies produced by modern scanners.
  • Finally, I have an interest in the calibration of robotic systems and their application in surgery.

All of these topics are multidisciplinary and I hold a joint appointment with the Department of Electrical and Computer Engineering and the Department of Mechanical Engineering to support this research.
