<br>
First of all, thank you for all your help.<br>
<br>
So, from the previous posts I was able to resample the CBCT image so that it<br>
lies in the direction of the Trajectory. So far so good. Now, I am trying to<br>
extract only a part of the volume in this resampled image. So, I figure that<br>
since I already calculated the direction, I could just set the size of the<br>
output image to be what I want in the "ResampleImageFilter" and it should<br>
work fine. However, when I do this, the extracted volume is in a different<br>
direction than I assumed it to be. For example,<br>
<br>
<<a href="http://itk-users.7.n7.nabble.com/file/n38228/Capture.png" rel="noreferrer" target="_blank">http://itk-users.7.n7.nabble.<wbr>com/file/n38228/Capture.png</a>><br>
<br>
In the above image, I assumed the part of the volume that I extract is<br>
actually in the direction shown in the "Green" line, however I instead get<br>
the volume along the "Red" line. Why is this so? The direction I calculate<br>
for the "ResampleImageFilter" was essentially along the "Green" line.<br>
<br>
Additionally, what I am trying to do, is this not possible with the<br>
"ResampleImageFilter"? Do I need to extract the volume using the<br>
"ExtractImageFilter" instead?<br>
