size=2 face="Courier New"><span style='font-size:10.0pt'>From what I understood this is not an issue with probefilter, rather with vtkImageReslice and vtkTransform. You have to move your resliceplane along the normal and always take a probe at the desired position. Since you feed the whole imagedata (volume) to the probe it can take samples at every position in the dataset. Hope I understood your question.<o:p></o:p></span></font></pre><pre><font
