I’m using OpenIGTLinkIF to stream tracking data from an NDI Aurora tracking system into Slicer. (I work at NDI.) I’m tracking a needle, and in Slicer 3.x was able to have the relevant 2D slices show based on the position of the needle tip, with the needle tip showing in the 2D images. I believe all this was controlled in the “Visualization/Slice Control” section of the OpenIGTLink module. It seems that in Slicer 4.4/4.10, the “Visualization/Slice Control” section is no longer there. Is there some way to do this in Slicer 4?
