Background:
- Accurate image guidance is crucial for augmented reality (AR) spinal surgery.
- A novel spatial registration method has been developed to meet this need.
Purpose of the Study:
- To propose and evaluate a spatial registration method for AR spinal surgery navigation.
Main Methods:
- Utilized grayscale-based 2D/3D registration technology.
- Registered preoperative CT images with intraoperative X-ray images for spatial alignment.
- Achieved fusion of virtual images with the real spine.
Main Results:
- Achieved a 90% success rate in spine model registration.
- Reported a surface registration error ranging from 0.361 to 0.612 mm.
- Obtained a total average surface registration error of 0.501 mm.
Conclusions:
- The 2D/3D registration method is suitable for AR spinal surgery navigation.
