Design Of A Computer Aided Surgical Navigation System Based On C-Arm

Abstract

Though the conventional C-arm fluoroscope is used in bone surgeries for decades, two outstanding disadvantages remain. One is that it is not well adapted to the image-guided orthopaedic surgery procedures. Another is exposure of patients and surgeons in the radiation environment are harmful. At present, computer aided surgical navigation system is more and more used in surgery, but it is only connected to MRI ( magnetic resonance imaging ) or CT (computerized tomography ). This research addresses these issues. Using the C-arm and binocular spatial position system to navigate, with the help of the computer, is studied in our laboratory. The new system is called CASNC (Computer Aided Surgical Navigation system based on C-arm). This system has not only potential to maximize the advantages of the conventional C-arm and accuracy of drilling, but also reduce surgeon and stuff in the operating theatre, especially patients suffering the X-ray radiation exposure.
