Hi, We are developing a navigation system for use with CT images and optically tracked tools. We’re using the volume reslice driver to reslice the image views in real-time with respect to tool position and orientation, but our surgeons would prefer to if the image was still (still resliced) and the…

These are all completely configurable. You need to set up your transform tree keeping in mind that the root of the transform tree is the renderer world coordinate system. So, objects in that coordinate system will be stationary in the viewers (unless of course you move the slice view plane or camera…

I’m not sure I totally understand your solution. Here is the transform tree: [image] For reslicing I set GuideTipToGuide as the driver. The CT (CT_crop) is the image of interest. From my understanding the root here is the RAS coordinate system, and the CT image is in that coordinate system? [imag…

[image] Prashant_Pandey: the root here is the RAS coordinate system, and the CT image is in that coordinate system? Exactly. This means that the CT image will be always stationary. For example, if you want your CT image to move in the 3D view when the patient moves then you can use the Track…

Sorry I think I wasn’t clear from the beginning. The CT is stationary in the 3D viewer as expected and as desired by our surgeons. However, the CT is not stationary in the red/yellow slices when using the volume reslice driver and setting the driver to GuideTipToGuide. Instead the tool model (‘Loca…

Volume reslice driver has modes that force the slice orientation to an anatomical direction and just take the position from the tool transform. You can display the tool model as projection to visualize out-of-plane parts of the model (configurable in Models module). You can also define custom rule…

Thanks, I will take a look at that example.
