title: Transorbital endoscopic image guidance.
abstract: Endoscopic orbital procedures are hindered by the difficulty in differentiating between orbital structures during those procedures. Image guidance during endoscopic orbital procedures may improve the outcome of orbital endoscopic procedures because real time image and physical space tracking information can be provided to the surgeons to help in the delivery of therapy to the orbit. The research plan proposes to study the feasibility of image guided endoscopic orbital procedures. Specifically this research will characterize both the random and spatial fiducial localization error of the magnetic tracker. We will also determine and optimal fiducial placement that will minimize the TRE at the optic nerve junction and also demonstrate and validate the use of the magnetic tracker for transorbital endoscopic image guidance.
