Intraoperative Fast Adaptive Focus Tracking Robotic OCT Enables Real‐Time Tumor Grading and Large‐Area Microvascular Imaging in Human Spinal Cord Surgery (Adv. Sci. 27/2025)

Fast Adaptive Focus Tracking Robotic Optical Coherence Tomography System The cover illustrates the fast adaptive focus tracking robotic optical coherence tomography (FACT-ROCT) system providing real-time, high-resolution imaging during spinal cord tumor surgery. The robotic-guided OCT probe scans over the surgical site, while the display reveals vascular and structural tumor features. This system enables intraoperative tumor grading and microvascular mapping, enhancing surgical precision and safety.
