[IGSTK-Users] Tracking Problem.

[Patrick Cheng]

Hi Ashwath,

It looks like a problem with the sequence of setting image landmarks and 
tracker landmarks.

Please follow the steps below and try it again:

1. After loading images using the NeedleBiopsy application. Make sure 
you go through the fiducial list in the drop down box and click on the 
image to set each fiducial point.



2. Connect to your tracker. After tracker initialization, there will be 
a pop-up box asking you to set tracker landmark points. Pointing your 
tracked probe to fiducial points following the same sequence as you set 
your image landmarks. Click on the button to confirm each tracker 
landmark point.

3. Click on registration, and it should start tracking if successful.

Patrick
