hallo David,<br><br>thank you for the answer,<br><div style="text-align: center;"><div style="text-align: left;">the distance between x-y is the same, the slice thickness can be different. In some series for example the first 50 files have a thickness of 1mm, the next 50 files a thickness of 2mm. <br>
Now I want to use VtkImageImageReslice to show the MPR viewes, must the data in VtkImageData have the same thickness???<br>or i have to calculate a new spacing for the serie which contains files with different thickness???<br>
<br>thank you<br>Martin<span id="result_box" class="short_text"><span style="background-color: rgb(235, 239, 249);" title="Schichtdicke"> </span></span><br></div><span id="result_box" class="short_text"><span style="background-color: rgb(235, 239, 249);" title="Schichtdicke"></span></span></div>

<div class="im">The Z spacing can be anything, the X, Y, and Z spacings do not have to<br>
be equal. All of the VTK classes that you mentioned will use the<br>
</div>spacing properly. Are you seeing squashed or stretched-looking<br>
images?<br>
