Drs. Ivan Yeoh, Per Reinhall, Martin Berg, Howard Chizeck and Eric Seibel received the American Society of Mechanical Engineers (ASME) Journal of Dynamic Systems, Measurement and Control (JDSMC) Rudolf Kalman Best Paper Award for their paper “Electromechanical Modeling and Adaptive Feedforward Control of a Self-Sensing Scanning Fiber Endoscope.”

Dr. Ivan Yeoh

The paper presents the first online-adaptive control strategy for the scanning fiber endoscope (SFE). The SFE was developed at the University of Washington (UW) Human Photonics Laboratory. It further advances current endoscopes (small cameras that are primarily used in medical diagnoses by physicians) by enhancing high-quality laser-based imaging technology. It uses an ultrathin and flexible endoscope, allowing physicians to circumnavigate difficult to reach internal tissues. The authors’ adaptive feedforward control strategy helps anchor SFE, showing marked improvements in scan accuracy over previous control methods and operating environment adaptability.

The Rudolf Kalman Best Paper Award is given annually by the Dynamic Systems and Control Division of ASME to the authors of the best paper published in the ASME JDSMC during the preceding year.

Yeoh received his Ph.D. in mechanical engineering at the UW. Professor Reinhall is chair of the UW Department of Mechanical Engineering. Professor Howard Chizeck is a faculty member in electrical engineering. Professors Berg and Seibel are faculty in mechanical engineering.
