Write DICOM series and keep original UID

[vpannetier-rebrain]

Hello,

I’m trying to write a DICOM series (slice by slice) using itk-wasm / write-image, but GDCM regenerates the StudyInstanceUID and SeriesInstanceUID even when these metadata fields are already present in the input image. I noticed there is a default boolean m_KeepOriginalUID in the itkGDCMImageIO class, but this option is not exposed in the JavaScript bindings.

Am I doing something wrong? Is there a workaround or a recommended solution?
Thank you in advance,
Best regards

Hi,

We could use a UID if it is on the input's metadata? Would that address your use case?

Hello,
thank you for your reply.

Yes, that's exactly what I need, so I can make sure that the StudyInstanceUID tag is shared between the different slices.
Thank you in advance,
Best regards

Hello,

I am following up on my question. Is a change planned for the future, or is there another way to do what I want to do?

Thank you in advance.

Hi @vpannetier-rebrain , a pull request with the proposed fix and a test are welcome. We can make this the default behavior -- if the input ITK-Wasm image metadata has a UID, then use it.
