Hi,
I am trying generate a dicom series from volume data.
How can should i give the patient position tag ,orientation tag and pixel spacing tag for each slice? Should I add them in a loop?
I could not find any examples for this. If any reference is there, it will be helpful.
Thanks
Hasna

Hello @Hasna,
As you haven’t specified if you are using SimpleITK or ITK, I’ll assume SimpleITK and point you to [this example](https://simpleitk.readthedocs.io/en/master/link_DicomSeriesFromArray_docs.html) of writing a DICOM series from array. Hopefully this is what you are looking for. If not, please provide additional details.

Hi @zivy I am using ITK. This is what i wanted. Is there any example code implemented in ITK?

Hi @Hasna,
I don’t think so. In any case all of the ITK examples can be [found here](https://itk.org/ITKExamples/src/index.html), so possibly there is one there.
@dzenanz knows this better than me, so possibly he points you in the right direction.

Hi @zivy,
I will go through this reference. Thanks a lot !!

How about [this example](https://itk.org/ITKExamples/src/IO/GDCM/ResampleDICOMSeries/Documentation.html)? If you are not starting from a DICOM input, I think you need to “invent” a patient and a study in order to write a DICOM series.
If you don’t need a series, can you try using a regular ITK writer and asking for a file name which ends with `.dcm`? Or explicitly setting `GDCMImageIO` on the writer?

Hi @dzenanz,
Thank you for the reference.
I am not starting from a dicom series.
If I use regular image series writer with filename ending with .dcm, the patient position and orientation tags are not updating. Anyways I am working using the reference you gave.
