  •   Name: Quantitative surgery
  •   Owner(s): MILOSAVLJEVIC Srdjan BARDOSI Zoltan FREYSINGER Wolfgang 
  •   Description: Exploring ways to provide certainty of resection borders by merging computer vison with computer-assisted intraoperative navigation, This project will integrate three-dimensional reconstructions of a surgical site obtained from live surgical views into preoperative imagery (CT, MR) and planning. “Real-time” reconstructions will be superimposed on volumetric data to allow determining the amount of tissue resected. Computer vision will be integrated to open-source IGSTK-based intraoperative navigation with a tracked Leica stereo-operating microscope for stereo-augmented reality guidance of surgeons.Funded by the Austrian National Bank, Jubilee Funds Project 16154 (2015 - 2018).
