Summary
Three-dimensional (3D) structured light offers an accurate and safe marker-free registration method for robot-assisted neurosurgery. This technique improves clinical efficiency and patient comfort in procedures like Ommaya reservoir implantation and stereotactic biopsy.
Area of Science:
- Neurosurgery
- Medical Imaging
- Robotics
Background:
- Surface-based facial scanning registration is crucial for robot-assisted neuronavigation surgery.
- It provides a marker-free method for aligning facial surfaces with imaging data.
- Three-dimensional (3D) structured light represents an advancement in this registration technique.
Purpose of the Study:
- To introduce 3D structured light as a novel registration method in robot-assisted neurosurgery.
- To evaluate the accuracy, efficiency, and safety of this technique.
- To analyze operative results for specific neurosurgical procedures.
Main Methods:
- Analysis of data from 47 patients undergoing robot-assisted Ommaya reservoir implantation (n=17) or stereotactic biopsy (n=30).
- Procedures utilized 3D structured light for registration from January 2022 to May 2023.
- Evaluation focused on accuracy, operative time, and patient outcomes.
Main Results:
- For Ommaya reservoir implantation: target point error 3.2 ± 2.2 mm, entry point error 3.3 ± 2.4 mm, duration 35.8 ± 8.3 min.
- For stereotactic biopsy: target point error 2.3 ± 1.3 mm, entry point error 2.7 ± 1.2 mm, duration 24.5 ± 6.3 min.
- The 3D structured light method demonstrated sufficient accuracy and safety.
Conclusions:
- 3D structured light technique enhances clinical efficiency in neurosurgery.
- It reduces patient discomfort due to its simpler, marker-free procedure.
- The method meets clinical requirements for puncture and navigation accuracy and safety.
