Hi all,
I am developing a stand alone program (not workbench plug-in) using MITK
which allows me to interactively position an instrument (its 3d model)
with respect to the patient (a CT scan volume). In this framework, I
would like to assure that the chosen configuration does not present any
collision between the tool (actually, a part of it) and the patient
body. Is there something in MITK for collision detection ?
The preliminary idea I have is to segment the body with an ITK filter
(threshold or region growing), import it in the scene as an mitkImage,
get its vtkPolyData and check the collision between the patient volume
and the tool with vtkIntersectionPolyDataFilter.
Do you think this could be a right way to proceed? Have you a more
appropriate solution or can you suggest me some example / article or
other references to read ? Actually, just a boolean result (collision /
not collision) would be already an acceptable result for me (and it
would speed up the process).
Any suggestion is more than appreciated. Thank you !
Best regards,
