New AI tool aligns surgical X-rays to 3D scans in seconds
A self-supervised framework called xvr can match two-dimensional intraoperative X-rays to a patient's own three-dimensional CT or MRI scan in seconds, without manual labelling. Described in Nature on 17 September 2026, the system trains a small neural network directly from each patient's preoperative scan using physics-based simulation. According to the study, xvr achieved high accuracy across diverse anatomical structures, imaging modalities and hospitals, in what the authors call the largest evaluation of this kind of registration on real fluoroscopy to date. A foundation model pretrained on thousands of whole-body scans can be fine-tuned to any body region in roughly five minutes.
Surgeons navigating catheters and robots in real time will have more accurate, faster image guidance during procedures on any part of the body.
