Live 3D Guidance in the Interventional Radiology Suite

¹ Department of Radiology, Division of Pediatric Interventional Radiology, Cincinnati Children's Hospital Medical Center, 3333 Burnet Ave., Cincinnati, OH 45229-3039.

OBJECTIVE. The development of a C-arm cone-beam CT unit coupled with flat detectors has markedly increased anatomic visualization capabilities for interventional radiology procedures. We present technology in which fluoroscopy and 3D imaging from a cone-beam CT-flat-detector C-arm unit are combined with an integrated tracking and navigation system. A description of the technology and representative clinical cases are presented.

CONCLUSION. This new combination further increases interventional radiologic capabilities because it provides real-time procedural evaluation and tracking.
