Operating system: window 7
To plan a needle insertion process, i need to load a needle in slicer and finding the transformation of the needle to obtain the position and orientation if the needle tip. I use the transformation module to achieve this purpose. But i found that the rotation of the needle around its axis affects the transformation module.
I need to know how can i omit the effect of the rotation around the needle axis?
I would be so appreciated if anyone could help me…
