How to validate the accuracy of a vision-based tracking instrument in 3D Slicer navigation?

Hi everyone,

I’m developing a vision-based tracking instrument and would like to use it for navigation in 3D Slicer. So far, I have completed the following steps:

  1. Installed the “IGT” module in 3D Slicer.
  2. Created a needle model and performed registration for the needle.
  3. While testing on a human model, the navigation appears accurate based on visual inspection.

My questions are:

  1. What should I pay attention to during this process to ensure tracking accuracy?
  2. How can I scientifically validate the localization and navigation accuracy of my instrument?
  • For instance, are there recommended tools, methods, or evaluation standards for this?
  • Should I use a phantom (calibration object) or known landmarks to measure errors?

Any advice on how to evaluate the performance of my tracking instrument would be greatly appreciated!

Thank you in advance for your help!
