Abstract: Biomedical Engineering is the most common field of sciences that relates to both doctors and engineers. With numerous biomedical challenges ahead, the bridging cooperation between doctors and engineers is growing in importance. The objective of this project is to research, design and develop a Real Time Three- Dimensional (3D) Surgical Scene for Natural Orifice Transluminal Endoscopic Surgery (NOTES). An accurate and sensitive system, that permits complex 3D visualisation and have no discernible lag are the main advantages, which spur developers and surgeons into research and development of such therapy procedure, known as Image Guided Therapy (IGT). Using magnetic position and orientation sensors, which are affixed to a flexible endoscope, 3D coordinates and orientation of the distal tip of the endoscope are known. From pre-operative medical imaging means, a 3D scene of the phantom could be created. By identifying appropriate landmarks, intra and pre-operative 3D scenes could be merged. The surgeon would have a real time view to visualise the position and orientation of the flexible scope (tracked tool) within the body. Intra-operative module (tracking system) would be the author’s main focus of the report. CT scans would be the referencing images. The softwares used are IGSTK and 3D Slicer. Main hardware is the NDI's Aurora® System. They will be built and integrated using Microsoft Visual Studio 2005 and Cross Platform Make (CMake). OpenIGTLinkTrackerBroadcasting application in IGSTKSandbox helps to connect 3D Slicer and Aurora® System (via OpenIGTLink IF and NeuroNav modules). The final product of this project is being established when feasibility of IGT Navigation System and Data Registration are demonstrated. With fine tuning, it can be applied in relation to “Real Time Three-Dimensional (3D) Surgical Scene for Natural Orifice Endoscopic Surgery”, whereby its needs are closely met.
