Abstract: Trauma and orthopedic surgeries that involve fluoroscopic guidance crucially depend on the acquisition of correct anatomy-specific standard projections for monitoring and evaluating the surgical result. This implies repeated acquisitions or even continuous fluoroscopy. To reduce radiation exposure and time, we propose to automate this procedure and estimate the C-arm pose update directly from a first X-ray without the need for a pre-operative computed tomography scan (CT) or additional technical equipment.
