Real-Time 3D Needle Guidance Using Dynamic Spiral OCT Scanning and Shape-Driven Pose Extraction in Retinal Interventions

Reliable microneedle guidance during subretinal injection remains a major clinical challenge. One of the reasons is that surgeons must infer the 3D position of the needle from a stereomicroscope that offers limited depth perception and from narrow B-scan iOCT cross-sections that cover only a fractio
