[IGSTK-Users] motion capture for tracking with Slicer 3d + PLUS

[Yaniv, Ziv Rafael (NIH/NLM/LHC) [C]]

Hello Vlad,

There are several companies that market tracking systems for medical applications (optical or electromagnetic), though NDI is the dominant player in this domain. A partial list includes:

NDI (they also own ascension):
http://www.ndigital.com/
http://www.ascension-tech.com/

ClaroNav:
http://www.claronav.com

Atracsys:
http://www.atracsys.com

Axios3D:

You also listed Medtronic Stealth Station. This is not a tracking system it is a complete navigation solution which uses optical tracking from NDI or medtronic's proprietary electromagnetic tracking.

All of the solutions are a combination of hardware and software (at a minimum a software API to interact with the device). NDI does the computations on their hardware, claron does them on the host machine. Both are equally good approaches.

Other companies that sell optical tracking solutions not geared towards medical:
http://www.ar-tracking.com/
http://www.optitrack.com/

With regard to building your own tracking system using 2-3 off the shelf video cameras, I would advise against this unless you don't require robustness and reliability which means you are not taking it into the clinical setting. Building a setup from scratch is not trivial - for instance, the spatial relationship between your camera sensors can change due to changes in temperature between the calibration setup and usage setting. This will effect your accuracy.

    hope this helps
          Ziv

p.s. Two additional pointers that may be of potential interest to you

2. A toy open source navigation system using a calibrated webcam (monocular tracking) we developed with IGSTK: http://yanivresearch.info/igiTutorial/igiTutorial.html

Hello.
We are going to make a cheap and flexible surgery tracking system based on 3d Slicer + PLUS.
So we have a question about optical tracking for instruments during operation.
Now we are looking for motion capture software which can match following requirements:

  *   Any compatible tracker device through OpenIGTLink interface.
  *   Any tracker device that are supported by the IGSTK toolkit, using IGSTK's OpenIGTLinkTrackingBroadcaster application.
  *   Receiving values of transforms from 3D Slicer application

We know about existing Generic pose tracking devices:

  *   Ascension electromagnetic tracking devices (and Ultrasonix SonixGPS)
  *   Claron MicronTracker optical pose tracker
  *   NDI Polaris and Aurora pose trackers
  *   NDI Optotrak Certus optical pose tracker
  *   Medtronic Stealth Station

But can we do the same job alternatively by using 2-3 videocams + appropriate software? Or the main function is in hardware?

Thank You!
