Endovascular catheterization is an intervention which offers a low risk alternative to open surgery in many patients. Today's interventions rely heavily on fluoroscopic imaging to guide …
Robotic C-arms are capable of complex orbits that can increase field of view, reduce artifacts, improve image quality, and/or reduce dose; however, it can be challenging to …
Purposes Surgical reduction of pelvic fracture is a challenging procedure, and accurate restoration of natural morphology is essential to obtaining positive functional outcome. The …
We develop a mathematical framework for the design of orbital trajectories that are optimal to a particular imaging task (or tasks) in advanced cone-beam computed tomography …
Cone-beam CT (CBCT) is increasingly common in guidance of interventional procedures, but can be subject to artifacts arising from patient motion during fairly long (~ 5–60 s) scan …

Intraoperative x-ray radiography/fluoroscopy is commonly used to assess the placement of surgical devices in the operating room (eg spine pedicle screws), but qualitative …
Abstract A 3D–2D image registration method is presented that exploits knowledge of interventional devices (eg K-wires or spine screws—referred to as' known components') to …
Purpose. A system for long-length intraoperative imaging is reported based on longitudinal motion of an O-arm gantry featuring a multi-slot collimator. We assess the utility of long …
