Methodology for the Identification of Needles Trajectories in Robotic Brachytherapy Procedure Using VR Technology

Abstract

Surgical robots, including those for brachytherapy procedure, require preoperative registration prior to use for needle placement procedures. Using a virtual environment for programming the needles trajectories allows a safer procedure for robotic brachytherapy, by avoiding vital structures and providing efficient penetration placement of radioactive seeds. In this paper is proposed a methodology based on Virtual Reality (VR) technologies that can be used to generate and optimize the needle trajectory in the pre-planning stage of the robotic brachytherapy procedure.
