Hi Dirk,<br>Although I am not sure if there is any class in ITK for this, but I think ITK SNAP has a class for volume image ray intersection @ InsightApplications/SNAP/Logic/Common/ImageRayIntersectionFinder<br>You could probably use that.<br>

Dear list,<br>
<br>
I'd like to follow a straight line through an image.<br>
The starting point of the line is outside the image, the end point is<br>
somewhere inside.<br>
What I need to know are the pixel indeces the line passed<br>
and also the length of the line in each pixel. (this is very important)<br>
<br>
The image will have anisotropic spacing (like 0.7 x 0.7 x 4)<br>
<br>
Can i do this with itkPolyLineParametricPath?<br>
I couldn't find any example code for that.<br>
<br>
<br>
Thanks,<br>
Dirk
