Summary
This study introduces ARView, an image-enhanced surgical navigation system for endoscopic sinus surgery (ESS). The ARView system achieves overlay accuracy of 2-3 mm, comparable to conventional systems, with registration needing further improvement.
Area of Science:
- Medical Imaging
- Surgical Navigation
- Otolaryngology
Background:
- Endoscopic sinus surgery (ESS) treats chronic sinusitis when medication fails.
- ESS relies on surgeon's hand-eye coordination due to lack of depth perception from endoscopes.
- Image-enhanced surgical navigation (IESN) can improve ESS accuracy and surgeon confidence.
Purpose of the Study:
- To develop and validate the ARView IESN system for rigid endoscopes used in ESS.
- To assess the performance of calibration, registration, and overlay steps in the ARView system.
Main Methods:
- Developed and validated the ARView IESN system for rigid zero-degree endoscopes.
- Presented interface, calibration, and registration methods (pre-operative and intra-operative).
- Quantitatively assessed system performance including calibration, registration, motion tracking, and overlay accuracy using CT data.
Main Results:
- Optimized object space errors of 0.025 +/- 0.013 mm for planar calibration.
- Target registration errors (TREs) of 2.3 +/- 0.4 mm near the region of interest.
- Tracking accuracy around 1.2 mm and object space overlay errors of 0.4 +/- 0.02 mm in a small volume.
Conclusions:
- The ARView system achieves overall overlay accuracy of 2-3 mm, aligning with conventional surgical navigation systems.
- Registration remains the primary area for improvement.
- Further investigation into the proposed photo-consistency method for registration is warranted.
