title: A novel field-of-view augmentation wand for C-arm computed tomography-like fluoroscopy-based intraoperative navigation new technology.
abstract: Intraoperative fluoroscopically based computed tomography, integrated with a navigation system, holds great potential for improving visualization and navigation in orthopedic procedures. However, a limited field of view generated by the fluoroscopically based computed tomography has imposed a serious limitation, especially for navigation-based procedures. The device presented in this article enables one to overcome the limitation of the small field of view. The device has been evaluated in vitro by five physicians and has been used successfully in one clinical case. In general, we have developed a simple, low-cost in-house device that helps overcome an intrinsic limitation of high-cost systems.
