Dear Arpit,
for this purpose you would need to project the tool onto the 2D image
plane. This could be done by a (new) image filter. To my knowledge,
unfortunately, there is no such image filter in MITK at the moment. But
such a feature would be very nice for the IGT module we thought about it
a number of times too. A good starting point to implement such a filter
might be the mitk::NeedleProjectionFilter from the ultrasound module. It
only projects a point at the moment (see the screenshot attached to this
mail), but maybe it can be extended to your needs. If you have time to
do so, we would appreciate contributing this to MITK.
Regards,
Alfred

Thanks Ingmar for your quick reply.
I would like to visualize the axis of the tool. This will help in
displaying direction of the tool in surgery while following a defined
trajectory.
I have attached an example with the mail. Yellow line shows the
trajectory & green line shows the location of tool.
Best Regards,
Arpit

Hi Arpit,
that looks like a regular setup of 2D and 3D widgets to me. What
do you want to visualize?
The widgets are setup by default to show 3 x 2D (sliced) and 1 x
3D widgets. So in the 2D views the tool is sliced as well.
You can easily change the rendering mode of a widget from 2D to
3D. But then you end up with a scene similar to your lower right
widget (yellow boarder).
So what do you want to show?

Ingmar

Hi,
I am facing problem with the visualization of navigation tool.
I am using NavigationDataObjectVisualizationFilter to connect
STL data with pointer tool navigation data.
I am getting pointer tip visible in all the views but not the
compete tool. It seems like the portion of pointer in the
slice is only visible. If I align the pointer parallel to any
of Axial/ Sagittal/ Coronal plane then I see the almost all
portion of the pointer. Even if I hide the image I still get
the same visualization of the pointer in all the views.
How can I visualize the complete geometry of the tool instead
of sliced portion? I have attached file for your reference.

Arpit
