How to set specific presentation contexts

[arai0101]

I have a problem. I am building a DICOM downloader with PyQt5. The peer PACS is SYNAPSE in the hospital. I want to retrieve CT images and I configure the presentation context, they are proposed and accepted for the SCU/SCP role. However, in the incoming associate-RQ PDU, the presentation context for CT images is not part of negotiation. I really appreciate if you can give me an advice. Thank you. Here is my code.

C-MOVE at PATIENT level

  def c_move(self):
    ae = AE()
    ae.ae_title = self.client_scu['aet'].encode('utf-8')
    ae.maximum_pdu_size = 0
    ae.supported_contexts = StoragePresentationContexts
    ae.add_requested_context(PatientRootQueryRetrieveInformationModelMove)
    ae.add_requested_context(CTImageStorage)
    # ae.add_requested_context(EnhancedCTImageStorage)
    ae.add_requested_context(UltrasoundImageStorage)
    ae.add_requested_context(SecondaryCaptureImageStorage)

    ds = Dataset()
    ds.QueryRetrieveLevel = 'PATIENT'
    ds.PatientName = self.selected_patient['PatientName']
    ds.PatientID = self.selected_patient['PatientID']
    total_images = self.selected_patient['total_images']

    self.download_patient_worker = DownloadPatientWorkerController(ae=ae,
                                                                   ds=ds,
                                                                   total_images=total_images,

Don't do this:

      for cx in self.assoc.accepted_contexts:
        cx._as_scp = True
        cx._as_scu = True
        print(cx)

Have you looked at the Q/R Move code example or the Move SCU application code?

The Move SCP controls which presentation contexts it asks for when requesting the association with the destination Storage SCP, all you can do is have a Storage SCP available which supports CT Image Storage or whatever it is you're trying to retrieve.

I'm not seeing any matches to your query in the log, so the Move SCP has nothing to send.

Also, that better not be an actual patient name and ID you've used.

Rude.
