摘要：

The C-arm fluoroscope is an indispensable intraoperative 2D imaging device for orthopaedic surgery. A recent technique known as virtual fluoroscopy (VF) enhances the fluoroscope's capability for image guided surgery by tracking optically the position of the C-arm, surgical instruments and the patient. Virtuality is achieved by overlay of surgical instruments onto one or more previously captured fluoroscopic images. This paper presents a new technique for determining the position and calibrating the geometry of a C-arm fluoroscope. This technique is based on a small registration phantom that is placed close to the patient whilst imaging. This paper also reports on a VF-based protocol for the placement of the femoral component for an Oxford unicompartmental knee prosthesis. A key benefit of VF is that it reduces considerably the radiation hazard of using a C-arm fluoroscope and it enhances the surgeon's ability to plan intraoperatively and implement surgery.
