<p class="MsoNormal">Finding out what DICOM fields to use for grouping frames is a complex topic. There is no universally accepted standard, the field(s) to use depend on scanner manufacturer, imaging modality, and imaging protocol.<o:p></o:p></p>

<p class="MsoNormal">Apparently SeriesInstanceUID does not help; sounds familiar. Maybe FrameNumber, SeriesNumber or AcquisitionNumber? If not, sorting slices on slice coordinate and AcquisitionTime could be done as a last resort. If you post two slices with
the same coordinate but belonging to different volumes, I will take look at it.<o:p></o:p></p>

<p class="MsoNormal">Hello,<br>
<br>
I have a set of Siemens series. In each series there is the same slice for different times.<br>
I would like to be able to reconstruct in itk each single volume (a complete volume for every time step).<br>
It is a couple of week that I’m trying how to do that…<br>
I understood that I should use some tag, but I’m not sure about which and my code is not working.<br>
<br>
Could you be so kind to give me a suggestion here?<br>
<br>
My regards,<br>
<br>
Sonia<br>
