After C-Move operation successful ?

[tariq2305]

I think I am missing theoretical concept of using dcmtk.

After successful sending C-Echo request and C-Find. I have called send MOVE request.

Console Response:

Code: Select all

D: ===================== INCOMING DIMSE MESSAGE ====================
D: Message Type                  : C-MOVE RSP

D: Handling C-MOVE Response

So here I can see my C-Move operation is successful. What is the next step I have to apply so that I can fetch DICOM images ?

Please help!!!

You should start or have already started a storescp which receives the the images.

There is a storescp example which receives the images and save it.

Hi!
I want to download all the images of a series.
But I am stuck in creating the dataset for sending the image download request. I don't know what tags/parameters , i have to set for downloading the images. Here is my code:

Code: Select all

    
OFList<QRResponse*> OFfindResponses; 
    
    DcmDataset req; 
    req.putAndInsertOFStringArray ( DCM_QueryRetrieveLevel, "IMAGE"); 
    req.putAndInsertOFStringArray ( DCM_SeriesInstanceUID, "1.2.840.113747.1078798801.1964.3000.1762082110160.0");
    req.putAndInsertOFStringArray ( DCM_StudyInstanceUID, "1.3.12.2.1107.5.2.12.21264.4.0.8969333128827685" );
    req.putAndInsertOFStringArray ( DCM_PatientID, "7Q6,^71" );
    req.putAndInsertOFStringArray ( DCM_SOPInstanceUID, "");
     
    T_ASC_PresentationContextID presID = findUncompressedPC(UID_FINDStudyRootQueryRetrieveInformationModel, scu); 
    if (presID == 0) 
    {
        DCMNET_ERROR("There is no uncompressed presentation context for Study Root FIND"); 
        return ; 
    } 
    result = scu.sendFINDRequest(presID, &req, &OFfindResponses); 
    if (result.bad()) 
    {
        DCMNET_ERROR("There is no uncompressed presentation context for Study Root FIND"); 
        return ; 
        
    } 
    else 
    { 
        
    } 
    presID = findUncompressedPC(UID_MOVEStudyRootQueryRetrieveInformationModel, scu); 
    if (presID == 0) 
    {
        DCMNET_ERROR("There is no uncompressed presentation context for Study Root FIND"); 
        return ; 
        
    } 
    OFListIterator(QRResponse*) instance = OFfindResponses.begin(); 
    Uint32 instanceCount = 1; 
    OFBool failed = OFFalse; 
    while (instance != OFfindResponses.end() && result.good()) 
    { 
        OFList<RetrieveResponse*> moveResponses;       //MOVEResponses moveResponses; 
        if ( (*instance)->m_dataset != NULL) //Il faut etre certain que ce n'est pas la derniere réponse, elle ne contient pas d'information 
        { 
            OFString imageID;
            result = (*instance)->m_dataset->findAndGetOFStringArray(DCM_SOPInstanceUID, imageID);
            
            // only try to get study if we actually have study instance uid, otherwise skip it 
           
            if (result.good()) 
            { 
                //      [NSThread detachNewThreadSelector:@selector(launchStoreSCP) toTarget:self withObject:nil];

                req.putAndInsertOFStringArray(DCM_SOPInstanceUID, imageID); 
                // fetches all images of this particular study 
                OFString OFmonAet = OFmonAet; 
                result = scu.sendMOVERequest(presID, MOVEAPPLICATIONTITLE, &req, NULL 
                                             // we are not interested into responses
                                             ); 
                
                if (result.good()) 
                { 
                    DCMNET_INFO("Received Image  #" << std::setw(7) << instanceCount << ": " << imageID);
                    instanceCount++;      
                } 
            } 
        } 
        instance++; 
    } 

Can anyone suggest me the exact tags/parameters to be set for image downloading ?

[omarelgazzar]

DcmDataset req;
req.putAndInsertOFStringArray ( DCM_QueryRetrieveLevel, "IMAGE");
req.putAndInsertOFStringArray ( DCM_SeriesInstanceUID, "1.2.840.113747.1078798801.1964.3000.1762082110160.0");
req.putAndInsertOFStringArray ( DCM_StudyInstanceUID, "1.3.12.2.1107.5.2.12.21264.4.0.8969333128827685" );
req.putAndInsertOFStringArray ( DCM_PatientID, "7Q6,^71" );
req.putAndInsertOFStringArray ( DCM_SOPInstanceUID, "");

This request dataset can be used to download list of images if you provide list of SOP instance UIDs to be downloaded in the unique key attribute DCM_SOPInstanceUID. The only difference between C-Find request dataset and C-Move request dataset is that in C-Move request dataset, you should be able to provide specific values for unique key attributes patient id, Study Instance UIDs, Series Instance UIDs and SOP Instance UIDs down to the level of query/retrieve.

Best Regards,
Omar

Hi Omar!
Thanks for your reply.
But, I am doing the same thing what u have suggested. After getting the DCM_SOPInstanceUID through C-Find request, I am providing the same DCM_SOPInstanceUID for c-move request through the code :

Code: Select all

OFString imageID;
            result = (*instance)->m_dataset->findAndGetOFStringArray(DCM_SOPInstanceUID, imageID);
            if (result.good()) 
            { 
                req.putAndInsertOFStringArray(DCM_SOPInstanceUID, imageID); 
                result = scu.sendMOVERequest(presID, MOVEAPPLICATIONTITLE, &req, NULL 
                                             // we are not interested into responses
                                             ); 
                if (result.good()) 
                { 
                    DCMNET_INFO("Received Image  #" << std::setw(7) << instanceCount << ": " << imageID);
                    instanceCount++;      
                } 

As output, it shows the status of move response is successful.
One more thing, I am running the code viewtopic.php?f=1&t=3213&p=12722#p12722 for receiving C-StoreRequests, saving files and sending the C-StoreResponse in background thread using the same MOVEAPPLICATIONTITLE and port.
But it's handleincomingrequest method is not being called.
I am little bit confused about whether I should use the same port or not for receiving C-StoreRequests.

[omarelgazzar]

Hello,
You should specify the application entity title (AET) to which you wish to store the images in the sendMoveRequest() using the parameter "moveDestinationAETitle". The SCP should be configured to associate this AET to a certain host (port, ip address) to initiate store request. You should use storescp to listen for incoming connections on the port number you used to configure the MOVE SCP. The port used for receiving store requests should be a different port from the one used for move request.

Hi Omar!
Thanks for reply.
I have done same thing . but still images are not being downloaded.
This is the complete code.

Can u plz tell what are the mistakes which I am doing here ?

[omarelgazzar]

Did you try to listen for incoming connections using storescp on the port you specified for the PACS?

[tariq2305]

Hi Omar!
Yaah, I am listening for incoming connection by calling startStoreSCP() method in background thread in viewdidload().
startStoreSCP() method is like this:

Code: Select all

-(void)startStoreSCP

       // DicomEmpfangen *scp; // put this in a headerfile if you use a class and not a main!
         scp = new DicomEmpfangen();
        scp->setPort(USERPEERPORT);
        scp->setAETitle(MOVEAPPLICATIONTITLE);
    NSString *pathname = [[NSBundle mainBundle] pathForResource:@"storescp" ofType:@"cfg"] ;
    const OFString path = (char * )[pathname UTF8String];
    if (scp->loadAssociationCfgFile(path).good())
        {
            NSLog(@"SCP-Config-File gefunden :-)");
            NSLog(@"dime-timeout: %@", scp->getDIMSETimeout());
            if (scp->setAndCheckAssociationProfile("Default").good())
            {
                // NSLog(@"listen gestartet um: %@", QTime::currentTime());
                NSLog(@"listen gestartet um");

                scp->setDIMSEBlockingMode(DIMSE_NONBLOCKING);

During execution it shows the alert box having message: "Do you want the applicatio to accept incoming network connectios?"


but, DicomEmpfangen::handleIncomingCommand(T_DIMSE_Message *msg, const DcmPresentationContextInfo &info) method is not being called .
I can't understand, why this is happenning.

To check that you are really listening on the right port you specified for the PACS, use echoscu or storescu to test your storescp application? The log you have shown indicates that the operation was successful. Also, If you have access to the PACS log, check it. You can use also dcmqrscp commandline tool for testing your cmove scu application.

Hi Omar!
Thanks again.

Actually, I have created a method for storescp in the same project , which i have called in the background thread.
As log shows , association is successful, but , i can' t undersatnd, why such type of reponse is coming at the end :
