<div>Hello Vlad,</div>
<div><br>
</div>
<div>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:</div>
<div><br>
</div>
<div>NDI (they also own ascension):</div>
<div>http://www.ndigital.com/</div>
<div>http://www.ascension-tech.com/</div>
<div><br>
</div>
<div>ClaroNav:</div>
<div>http://www.claronav.com </div>
<div><br>
</div>
<div>Atracsys:</div>
<div>http://www.atracsys.com</div>
<div><br>
</div>
<div>Axios3D:</div>
<div>http://axios3d.com/EN/index.html</div>
<div><br>
</div>
<div>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.</div>
<div><br>
</div>
<div>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.</div>
<div><br>
</div>
<div>Other companies that sell optical tracking solutions not geared towards medical:</div>
<div>http://www.ar-tracking.com/</div>
<div>http://www.optitrack.com/</div>
<div><br>
</div>
<div>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. </div>
<div><br>
</div>
<div> hope this helps</div>

<div>p.s. Two additional pointers that may be of potential interest to you</div>

<span style="font-weight:bold">Subject: </span>[IGSTK-Users] motion capture for tracking with Slicer 3d + PLUS<br>
</div>
<div><br>
</div>
<div>
<div>
<div dir="ltr">Hello.
<div>We are going to make a cheap and flexible surgery tracking system based on 3d Slicer + PLUS.</div>
<div>So we have a question about optical tracking for instruments during operation.</div>
<div>Now we are looking for motion capture software which can match following requirements:</div>
<div>
<ul>
<li>Any compatible tracker device through OpenIGTLink interface.<br>
</li><li>Any tracker device that are supported by the IGSTK toolkit, using IGSTK's OpenIGTLinkTrackingBroadcaster application.<br>
</li><li>Receiving values of transforms from 3D Slicer application<br>
</li></ul>
<div>We know about existing Generic pose tracking devices:<br>
<ul>
<li>Ascension electromagnetic tracking devices (and Ultrasonix SonixGPS)<br>
</li><li>Claron MicronTracker optical pose tracker<br>
</li><li>NDI Polaris and Aurora pose trackers<br>
</li><li>NDI Optotrak Certus optical pose tracker<br>
</li><li>Medtronic Stealth Station<br>
</li></ul>
</div>
<div>But can we do the same job alternatively by using 2-3 videocams + appropriate software? Or the main function is in hardware?</div>
<div><br>
</div>
<div>Thank You!</div>
