Query: Conceptual Design and Preliminary Results of a VR-based Radiation Safety
  Training System for Interventional Radiologists   Recent studies have reported an increased risk of developing brain and neck
tumors, as well as cataracts, in practitioners in interventional radiology
(IR). Occupational radiation protection in IR has been a top concern for
regulatory agencies and professional societies. To help minimize occupational
radiation exposure in IR, we conceptualized a virtual reality (VR) based
radiation safety training system to help operators understand complex radiation
fields and to avoid high radiation areas through game-like interactive
simulations. The preliminary development of the system has yielded results
suggesting that the training system can calculate and report the radiation
exposure after each training session based on a database precalculated from
computational phantoms and Monte Carlo simulations and the position information
provided in real-time by the MS Hololens headset worn by trainee. In addition,
real-time dose rate and cumulative dose will be displayed to the trainee by MS
Hololens to help them adjust their practice. This paper presents the conceptual
design of the overall hardware and software design, as well as preliminary
results to combine MS HoloLens headset and complex 3D X-ray field spatial
distribution data to create a mixed reality environment for safety training
purpose in IR.
