Parallax of the proper calyx with c-arm is a core learning objective. Existing training systems use virtual reality(VR) or fluoro-assisted biologic and synthetic models. VR models have limitations and are expensive and fluoroscopy is impractical and is associated with unnecessary exposure to radiation. We report the development and initial validation of a fluoro-less percutaneous renal access trainer. METHODS A mini C-arm was designed and 3D printed. Two videocameras were mounted on the anterior and posterior portion of the C. The C was designed to tilt and rainbow. A clear flank model was created with a silicon material with a cast of a University of Minnesota SimPORTAL calyceal model in it filled with fluid. The silicon model has been then covered with a "blue screen" skin-like, colored material and provided with a physical reproduction of the 10th-12th ribs. The two cameras have been connected to a computer for image processing to produce the final on-screen image. RESULTS The C-arm navigation trainer has face and content validity for training percutaneous access. It does so successfully without radiation exposure. The novel double camera system and the image processing software were able to obtain visual information enough to accomplish correctly the training tasks, without expensive additional 3d motion tracking technologies. CONCLUSIONS The fluoroscopy-less C-arm navigation trainer accurately replicates the functions of a real X-ray system, without any radiation exposure related issues, regardless the time it takes to complete the training sessions. The usability of a perc model, as well as of any other specifically designed anatomical silicon models, make it a low cost, feasible instrument for training. © 2014FiguresReferencesRelatedDetails Volume 191Issue 4SApril 2014Page: e173 Peer Review Report Advertisement Copyright & Permissions© 2014MetricsAuthor Information Domenico Veneziano More articles by this author Arthur Smith More articles by this author Troy Reihsen More articles by this author Jason Speich More articles by this author Robert Sweet More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
