Interventional C-arm imaging is crucial to percutaneous orthopedic proceduresas it enables the surgeon to monitor the progress of surgery on the anatomylevel. Minimally invasive interventions require repeated acquisition of X-rayimages from different anatomical views to verify tool placement. Achieving andreproducing these views often comes at the cost of increased surgical time andradiation dose to both patient and staff. This work proposes a marker-free"technician-in-the-loop" Augmented Reality (AR) solution for C-armrepositioning. The X-ray technician operating the C-arm interventionally isequipped with a head-mounted display capable of recording desired C-arm posesin 3D via an integrated infrared sensor. For C-arm repositioning to aparticular target view, the recorded C-arm pose is restored as a virtual objectand visualized in an AR environment, serving as a perceptual reference for thetechnician. We conduct experiments in a setting simulating orthopedic traumasurgery. Our proof-of-principle findings indicate that the proposed system candecrease the 2.76 X-ray images required per desired view down to zero,suggesting substantial reductions of radiation dose during C-arm repositioning.The proposed AR solution is a first step towards facilitating communicationbetween the surgeon and the surgical staff, improving the quality of surgicalimage acquisition, and enabling context-aware guidance for surgery rooms of thefuture. The concept of technician-in-the-loop design will become relevant tovarious interventions considering the expected advancements of sensing andwearable computing in the near future.
