How to read incoming dataset from c-find?

Hello again! One final piece of the application I’m writing is to perform a c-find to query for patient info, study info and to get all series under a patient/study. I was wondering in the handle_find handler, on how to read the incoming data set? When I do a

def handle_find(event):
  ds = event.identifier
  print (ds)
  print ('hello world')
  return

Nothing regarding this dataset is printed to the screen. Here is the set up code:

handlers = [(evt.EVT_C_FIND, handle_find)]

ae = AE()
ae.ae_title = pacsLocalAETitle
ae.add_supported_context(PatientRootQueryRetrieveInformationModelFind)
scp = ae.start_server(('', int(pacsLocalPort)), block=False, evt_handlers=handlers)

ae.ae_title = pacsLocalAETitle
ae.add_requested_context(PatientRootQueryRetrieveInformationModelFind)
assoc = ae.associate(pacsServerHost, int(pacsServerPort), ae_title=pacsServerAETitle)

if assoc.is_established:
    ds = Dataset()
    ds.QueryRetrieveLevel = 'PATIENT'
    ds.PatientID = patientIDResponse
    response = assoc.send_c_find(ds, PatientRootQueryRetrieveInformationModelFind)

    for (status, identifier) in response:
        pass

    assoc.release()

Attached is the output log file received. I simply would like to view fields such as name, sex, birthdate, etc… I would also like to view a study level response and a series level response too (separate calls, but next things to do after this). Thanks!

I think you just want a Find SCU, in which case the responses to your query are in the response generator as (status, identifier). You don’t need the Find SCP, this should be sufficient:

ae = AE()
ae.ae_title = pacsLocalAETitle
ae.add_requested_context(PatientRootQueryRetrieveInformationModelFind)
assoc = ae.associate(pacsServerHost, int(pacsServerPort), ae_title=pacsServerAETitle)
if assoc.is_established:
    ds = Dataset()
    ds.QueryRetrieveLevel = 'PATIENT'
    ds.PatientID = patientIDResponse
    response = assoc.send_c_find(ds, PatientRootQueryRetrieveInformationModelFind)

    for (status, identifier) in response:
        # If `Pending` status, print response
        if status and status.Status in [0xff00, 0xff01]:
            print(identifier)

    assoc.release()

The evt.EVT_C_FIND handler is only required when you’re acting as a Find SCP (i.e. people are sending you queries).
