Title: Augmented Environments for Guiding Surgery Inside the Beating Heart
Time: Thursday, January 26, 2012, at 2:30-3:30 pm
Location:Queen’s University, Dupuis Hall – 215
Speaker: Dr. Terry Peters (PhD, FCCPM, FAAPM, FIEEE, FACPSEM, FMICCAI, F Inst P, C Phys), Scientist, Robarts Research Institute, Professor Medical Imaging, Medical Biophysics, Biomedical Engineering, University of Western Ontario
Abstract: Surgical procedures often have the unfortunate side-effect of causing the patient significant trauma while accessing the target site. Indeed, in some cases the trauma inflicted on the patient during access to the target greatly exceeds that caused by performing the therapy. Heart disease has traditionally been treated surgically using open chest techniques with the patient being placed “on pump” – i.e. their circulation being maintained by a cardio-pulmonary bypass or “heart-lung” machine. Recently, techniques have been developed for performing minimally-invasive interventions on the heart, obviating the formerly invasive procedures, that rely on pre-operative mages, combined with real-time images acquired during the procedure. Our approach is to register intra-operative images to the patient, and use a navigation system that augments intra-operative ultrasound with virtual models of instrumentation that has been introduced into the chamber through the heart wall. This presentation will illustrate the problems associated with traditional ultrasound guidance, and review the state of the art in real-time 3D cardiac ultrasound technology. In addition, it will discuss the implementation of an image-guided intervention platform that integrates real-time ultrasound with a virtual reality environment, bringing together the pre-operative anatomy derived from MRI or CT, representations of tracked instrumentation inside the heart chamber, and the intra-operatively acquired ultrasound images. The critical role of an Augmented Reality environment will be illustrated with its application in a new beating-heart valve repair procedure.
Speaker Bio: Dr. Terry Peters is a Scientist in the Imaging Research Laboratories at the Robarts Research Institute (RRI), London, ON, Canada, and Professor in the Departments of Medical Imaging and Medical Biophysics at the University of Western Ontario, as well as a member of the Graduate Programs in Neurosciences and Biomedical Engineering.. Dr. Peters received his graduate training at the University of Canterbury in New Zealand where his PhD work dealt with fundamental issues in Computed Tomography image reconstruction, For the past 30 years, his research has focused on the application of computational hardware and software to medical imaging modalities in surgery and therapy. Dr. Peters has authored over 200 peer-reviewed papers and book chapters, a similar number of abstracts, and has delivered over 180 invited presentations.
