Learning by X-ray: When Surgical Robots Teach Themselves to See in Shadows
X-rays are useful because they are cheap, familiar, and already sitting in the operating room. They are also, inconveniently, shadows. That is the central tension in Investigating Robot Control Policy Learning for Autonomous X-ray-guided Spine Procedures, a paper that asks whether a robot policy can plan vertebroplasty cannula trajectories from only bi-planar X-ray views—one anterior-posterior view, one lateral view—without CT-based navigation, registration, or a lovingly over-engineered suite of intra-operative infrastructure.1 ...
