No, I tryed to resample a different 3D DICOM image.<br>Saturday afternoon ITK mailing list solved my problems with ResampleFilter: I didn't do the ''reader->Update()''before asking image's dimensions, so it was naturally that my code said me that it was a 0x0x0 image... ;-)<br>So, thanks a lot to Insight-users (expecially to
<span id="PresenceContainer">

<br>Thanks.<br>
I tryed to do what you said me but now I've a new problem.... I wanted
to preserv the original x and y dimension of my image and only reslice
it; I've to use this resample filter with different images and so I
want a more general possible code.... so I try to do this:<br>
<br>
#include <itkImageIORegion.h> <br>
[...]<br>
<br>
InputImageType::Pointer image = reader->GetOutput();<br>
SizeType imageSize = image->GetLargestPossibleRegion().GetSize();<br>
<br>
but when I've this error:<div class="ecxim"><br>
<br>
terminate called after throwing an instance of 'itk::ExceptionObject'<br>
what(): /usr/local/include/InsightToolkit/IO/itkImageFileWriter.txx:271:<br></div>
itk::ERROR: ImageFileWriter(0x8956220): Largest possible region does
not fully contain requested paste IO regionPaste IO region:
ImageIORegion (0xbfcc9ba8)<div class="ecxim"><br>

Dimension: 3<br>
Index: [0, 0, 0]<br></div>
Size: [0, 0, 50]<br>
<br>
Aborted<br>
<br>
Could someone help me to solve this problem?<br>
Thanks<br>

Hi everyone<br>I'm new in itk....so, sorry for my (maybe stupid) questions.<br><br>I have to resample a 3D US image (it is a 97 frames image and I want to reduce its frame-number to 50).<br>I tried to adapt ResampleImageFilter (Examples/Filtering/ResampleImageFilter.cxx.) for 3D image. I wanted to run it to see how that filter works but I've this error:<br>
