Autonomous Skeletal Landmark Localization towards Agentic C-Arm Control

Apr 20, 2026

This study addresses the frequent need for manual intervention in C-arm repositioning during emergency procedures, which often delays treatment. The authors propose a novel approach that leverages a fine-tuned multimodal large language model (MLLM) to autonomously localize skeletal landmarks by integrating synthetic and real X-ray data during training. Incorporating clinical feedback enables dynamic C-arm navigation. Evaluated on two datasets, the method achieves landmark localization accuracy comparable to state-of-the-art deep learning models while demonstrating superior reasoning and spatial awareness capabilities. These attributes facilitate error correction and sequential adjustments, substantially enhancing procedural automation in fluoroscopic guidance.

Automated C-Arm Positioning via Conformal Landmark Localization

Oct 17, 2025

This study addresses the high radiation exposure and low efficiency associated with manual C-arm positioning in fluoroscopy-guided surgery by proposing a fully automated method for 3D anatomical landmark localization. Methodologically, we design an end-to-end deep network that takes a single X-ray image as input and directly predicts a 3D displacement vector to the target anatomical landmark. To enhance anatomical plausibility, we introduce skeletal pose regularization and a probabilistic loss function; further, we integrate conformal prediction to quantify both aleatoric and epistemic uncertainty, yielding well-calibrated 3D confidence regions. Trained on DeepDRR-synthesized data, our approach achieves sub-centimeter accuracy (mean error <6 mm) across multiple network architectures, with empirically validated coverage of predicted intervals. To the best of our knowledge, this is the first work to jointly incorporate conformal prediction and anatomical constraints for autonomous C-arm navigation—significantly improving system safety, reliability, and clinical applicability.
