Add PACS communication

[faltunik]

Heyy Team, I am interested in the project titled "Add PACS communication". Please recommend me an existing issue related to this project. Additionally, if any previous attempt was made, can you guys please share the main hurdles, and code link?
Thanks

We already have a initial GUI to this part https://github.com/invesalius/invesalius3/blob/master/invesalius/gui/import_network_panel.py. You need to install a PACS server like Orthanc https://www.orthanc-server.com/. GDCM, the library we use to read DICOM files, has a little tool to communicate with a PACS called gdcmscu you can use it from the command line. In Python you can use this module from GDCM.

Heyy @tfmoraes , For communicating with remote PACS, can we use Orthanc REST API?

I do believe that pynetdicom offers more functionality than gdcm library and also pynetdicom documentation is much better.

Is there any other reason to use GDCM library other than the fact that we are using it for handling dicom files?

Thanks

@faltunik I saw some days ago that Orthanc has as REST API. It seems to be easier to work. But our idea is to offer support to other PACS server too. Other open-source PACS server much used is DCM4Che. So, I think, it's better to use the DICOM protocol.

Yeah, GDCM documentation is not so good as pynetdicom. We prefer GDCM because we use GDCM to read DICOM files. If possible, it's better to use GDCM.

Heyy @tfmoraes sir, are we planning to provide the option to anonymize the DICOM files at the time of Upload. Can you please provide guidance on which DICOM tags can be anonymized in order to maintain the privacy of patient information?

[tfmoraes]

GDCM has a list of basic tags to anonymize https://github.com/malaterre/GDCM/blob/bea26dd820b46fd71bda811839025856c4886819/Source/MediaStorageAndFileFormat/gdcmAnonymizer.cxx#L36-L85

You can use this list in Python something like this:

r = gdcm.ImageReader()
r.SetFileName("dicom_file")
ano = gdcm.Anonymizer()
ano.SetFile(r.GetFile())
for tag in ano.GetBasicApplicationLevelConfidentialityProfileAttributes():
    ano.Empty(tag)

Thanks for response Sir.
