Summary
Image guidance can improve endoscopic orbital procedures by providing surgeons with real-time tracking. This study validates magnetic trackers for enhanced precision in transorbital endoscopic image guidance.
Area of Science:
- Ophthalmology
- Medical Imaging
- Surgical Navigation
Background:
- Endoscopic orbital procedures face challenges due to difficulties in differentiating orbital structures.
- Real-time image guidance can potentially improve surgical outcomes by providing surgeons with spatial tracking information.
Purpose of the Study:
- To investigate the feasibility of image-guided endoscopic orbital procedures.
- To characterize fiducial localization errors of magnetic trackers.
- To determine optimal fiducial placement for minimizing tracking reference error (TRE) at the optic nerve junction.
Main Methods:
- Characterizing random and spatial fiducial localization error of a magnetic tracker.
- Evaluating fiducial placement strategies to minimize TRE.
- Validating the use of magnetic trackers for transorbital endoscopic image guidance.
Main Results:
- The study will characterize magnetic tracker performance.
- Optimal fiducial placement will be identified to enhance accuracy.
- The system's utility for transorbital endoscopic image guidance will be demonstrated.
Conclusions:
- Image-guided endoscopic orbital surgery is feasible.
- Magnetic trackers offer a viable solution for real-time spatial tracking.
- This technology has the potential to improve the precision and safety of orbital procedures.

Endoscopic Procedures III: Video Capsule Endoscopy
Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers, unexplained...
Endoscopic Procedures V: ERCP
Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.
