Healthcare is changing at a very rapid pace. So does its attendant complexity and ever-increasing reliance on high technology support.  Simulation in healthcare, where sophisticated, technology-based methods are used in education of healthcare professionals and in treatment of patients, is becoming a recognized branch of knowledge and practice. Such methods require a new generation of engineers, computer scientists, systems designers, modelers, and physicians to integrate medical and technical domains. This talk will provide an overview of healthcare simulation, computing and engineering technologies as applied to surgical training. A historical perspective will be given, followed by the discussion of how simulation helps in gaining professional competency and how it helps improve healthcare outcomes.  A new surgical training and assessment system that provides sensing and reasoning capabilities in laparoscopy education will then be discussed. Laparoscopy is a surgical technology that can minimize recovery time and postoperative pain. However, with this procedure surgeons lose many of the tactile and visual cues that they rely upon in conventional surgery, thus it is of paramount importance that they initially train in a non-patient based setting.  The system, called CAST (Computer Aided Surgical Trainer) implements sensors, image processing, machine learning, and augmented reality techniques to provide real-time guidance and training assistance.  Future research work will focus on developing the technology as a robotic surgical assistant system for use in the operating room.



Dr. Jerzy Rozenblit is a University Distinguished Professor and Raymond J. Oglethorpe Endowed Chair in the Electrical and Computer Engineering at The University of Arizona. He also holds a joint appointment as Professor of Surgery in the College of Medicine. During his tenure, he has established the Model Based Design Laboratory with major projects in design and analysis of complex, computer based systems, software engineering, and symbolic visualization, and computer guided, minimally invasive surgery. The projects have been funded by the National Science Foundation, US Army, Siemens, Infineon Technologies, NASA and other entities. Currently, his key research focus is on developing effective, virtual coaching for surgical training. He has founded the Life Critical Computing Systems Initiative intended to improve the reliability and safety of technology in life critical applications. He holds the PhD (1985) and MSc (1983) degrees in Computer Science from Wayne State University. He is a Fellow of the Society for Computer Simulation International.
