C-Store handler is not triggered

[jaspreetsingh6993]

Hello folks, I am new to dicom, facing issues when I am trying to start SCP server and trying to save the dicom files in custom location. I tried same with some third party listener I received the images but C-store handler is not getting triggered and when I tried starting SCP from pynetdiocm itself I am not receiving the files and MOVE SCP response is showing success.

Below is the code, Hidden the IP and sensitive details:

import os
import pandas as pd
import pydicom
from pydicom.dataset import Dataset, FileDataset
from pynetdicom import AE, evt, StoragePresentationContexts, debug_logger
from pynetdicom.sop_class import PatientRootQueryRetrieveInformationModelMove
from pynetdicom.transport import AssociationServer
import time
debug_logger()

    # Implement a handler for evt.EVT_C_STORE
def handle_store(event):
    """Handle a C-STORE request event."""
    # Decode the C-STORE request's *Data Set* parameter to a pydicom Dataset
    ds = event.dataset
    # Add the File Meta Information
    ds.file_meta = event.file_meta
    fpath='\\xyz.file.core.windows.net\abc\test\'
    # Save the dataset using the SOP Instance UID as the filename
    filename = os.path.join(fpath,ds.StudyInstanceUID)
    print(filename)
    os.makedirs(os.path.dirname(filename), exist_ok=True)
    ds.save_as(filename+ds.SeriesInstanceUID+'.dcm')

    # Return a 'Success' status
    return 0x0000

handlers = [(evt.EVT_C_STORE, handle_store)]

study_df = pd.read_csv('test.csv')
study_df.drop(columns=['accession_num'], inplace=True)
study_df = study_df.drop_duplicates()
study_list = study_df.values.flatten().tolist()
study_log = []
status_log = []

ae = AE(ae_title=b'ABC_RESEARCH')
ae.add_requested_context(PatientRootQueryRetrieveInformationModelMove)
ae.supported_contexts = StoragePresentationContexts
scp = ae.start_server(("127.0.0.1", 104), block=False, evt_handlers=handlers)

for i in study_list:
    ds = Dataset()
    ds.QueryRetrieveLevel = 'STUDY'
    ds.StudyInstanceUID = i
    responses = []
    assoc = ae.associate('xxx.xxx.xxx.xx', 105, ae_title='RESEARCH-ALL-QR')
    if assoc.is_established:

        responses = assoc.send_c_move(ds,'ABC_RESEARCH', PatientRootQueryRetrieveInformationModelMove )

        for (status, identifier) in responses:
            if status:
                if status.Status==0:

                    study_log.append(i)
                    status_log.append('success')
                elif status.Status==65280:

                    pass
                else:
                    study_log.append(i)
                    status_log.append('failed')

        assoc.release()
    else:
        study_log.append(i)
        status_log.append('Association issue')

log_df=pd.DataFrame({'study_uid':study_log,'status':status_log})
log_df.to_csv('test_log.csv', index=False)
scp.shutdown()

You have the received files saved as ds.save_as(filename+ds.SeriesInstanceUID+'.dcm'), however the Series Instance UID is not unique for each SOP Instance. You probably want something like ds.save_as(filename+ds.SOPInstanceUID+'.dcm') instead

[jaspreetsingh6993]

Thanks for your response, I tried with ds.save_as(filename+ds.SOPInstanceUID+'.dcm') as well but no luck.

[scaramallion]

That's weird, something is definitely receiving the datasets. Are you sure that the PACS is configured with the correct details for the destination SCP (and that there's not already a destination with the AE title of ABC_RESEARCH)?

@jaspreetsingh6993 did you resolve your issue?
