Images illustrate the fluoro-CT matching technique for registration. (A) The operating room setup for fluoro-CT matching for Patient 12 is shown. Although two-plane fluoroscopic images are being taken, the data are instantly exported to the navigation platform (right side of picture) for fluoro-CT matching automatically. (B) The fluoroscopic image as seen on the C-arm monitor is shown. The dots are the reference points on the attached “phantom.” (C) An integrated view of fluoro-CT images as seen on the navigation monitor is shown. The preoperative plan, three-dimensional (3D) CT images, fluoroscopic views, two-dimensional CT images, and intraoperative surgical tools can be visualized in real-time simultaneously.
