tools/create-dicom - Unable to determine the SOP class/instance for C-STORE

[Bryan Dearlove]

Good Day All, 

I am using tools/create-dicom using a PNG to create a DICOM image, unfortunately when I try to send this to another server, I am getting an error:

DicomUserConnection: Unable to find the SOP class and instance: Unable to determine the SOP class/instance for C-STORE with AET AETDESTINATION

Here is the JSON I am using to create the study:

"Tags": {

        "Modality": "OT",

        "PatientName": "LASTNAME^FIRSTNAME",

        "PatientID": "PATIENTID",

        "SeriesDescription": "Prior Study Placeholder",

        "StudyDescription": "DESCRIPTION",

        "StudyDate": "20210705",

        "StudyTime": "124511.000000",

        "AccessionNumber": "ACCESSION",

        "PatientSex": "M",

        "PatientBirthDate": "20150412"

It looks as though I am getting: 0002,0002 (MediaStorageSOPClassUID): 1.2.276.0.7230010.3.1.0.1

I am not familiar with it, and assuming the PACS is rejecting this?

Please share a sample DICOM file for review.

There is a setting in the orthanc.json config file to accept all SOP classes.  Also, I think you can explcitly set the SOPClassID in the tags if you want.

This might be relevant also:  This might apply as well:  https://forum.dcmtk.org/viewtopic.php?t=871

    // Whether Orthanc accepts to act as C-Store SCP for unknown storage

Hello,

You simply have to add the "SOP Class UID" (0008,0016) tag, which is mandatory for transfers using the DICOM protocol. For instance, in Python:

import json
import requests

instance = requests.post('http://localhost:8042/tools/create-dicom', json.dumps({

    "Tags": {
        "Modality": "OT",
        "PatientName": "LASTNAME^FIRSTNAME",
        "PatientID": "PATIENTID",
        "SeriesDescription": "Prior Study Placeholder",
        "StudyDescription": "DESCRIPTION",
        "StudyDate": "20210705",
        "StudyTime": "124511.000000",
        "AccessionNumber": "ACCESSION",
        "PatientSex": "M",

        "PatientBirthDate": "20150412",
        "SOPClassUID": "1.2.840.10008.5.1.4.1.1.7",
    }})).json() ['ID']
