Can not get the PatientName,PatientId...

[visDicare]

Hi all,
I use the example:http://support.dcmtk.org/wiki/dcmtk/how ... cu-example to query information from the public DICOM server http://www.dicomserver.co.uk .
And I modify the example like below:

Code: Select all

	/* Assemble and send C-FIND request */ 
	OFList<QRResponse*> findResponses; 
	DcmDataset dataSet;  
	dataSet.putAndInsertOFStringArray(DCM_QueryRetrieveLevel, "SERIES"); 
	dataSet.putAndInsertOFStringArray(DCM_PatientID, patientId);
	dataSet.putAndInsertOFStringArray(DCM_PatientName, patientName);                
	dataSet.putAndInsertOFStringArray(DCM_PatientSex, "");                     
	dataSet.putAndInsertOFStringArray(DCM_PatientBirthDate, ""); 
	dataSet.putAndInsertOFStringArray(DCM_StudyID, "");
	dataSet.putAndInsertOFStringArray(DCM_StudyDate, this->ByDate);            
	dataSet.putAndInsertOFStringArray(DCM_Modality, this->ByModality); 
	dataSet.putAndInsertOFStringArray(DCM_StudyTime, this->ByTime); 
	dataSet.putAndInsertOFStringArray(DCM_SeriesNumber, "");
	dataSet.putAndInsertOFStringArray(DCM_SeriesInstanceUID, "");

I set the DCM_QueryRetrieveLevel to "SERIES", but the patient Id/Name/Sex/Bithdate/StudyId/StudyData are all none.
I read the Dicom standard Part-4 Annex C, and find the above attributes not belong to series level, I think it is the root cause

but I use the same code to access the local sever(DCM4CHEE), I can get all the information!

So Why?

Thanks!

That's right.

This is something you should ask the author(s) of DCM4CHEE.

Thanks!

This is something you should ask the author(s) of DCM4CHEE.

You mean the DCM4CHEE does not match with the DICOM standard?

Oh, my god!

By the way,

If I set the DCM_QueryRetrieveLevel to "STUDY" and get the StudyInstanceUID, and then use it to query Series number, the run time will more than 40 times.
The code like below:

Code: Select all

   OFList<QRResponse*> findResponses; 
   DcmDataset dataSet;  
   dataSet.putAndInsertOFStringArray(DCM_QueryRetrieveLevel, "STUDY");
           
   scu.sendFINDRequest(presID, &dataSet, &findResponses);
   OFListIterator(QRResponse*) response = findResponses.begin();
   OFString uid = "";
	while (response != findResponses.end())
	{ 
		// be sure we are not in the last response which does not have a dataset 
		if((*response)->m_dataset != NULL) 
		{   
		     uid = FindAndGetOFStringArray(DCM_StudyInstanceUID, (*response)->m_dataset);
			
           newDataSet.putAndInsertOFStringArray(DCM_QueryRetrieveLevel, "SERIES");
	        newDataSet.putAndInsertOFStringArray(DCM_StudyInstanceUID, uid);
	        newDataSet.putAndInsertOFStringArray(DCM_SeriesNumber, "");
	        newDataSet.putAndInsertOFStringArray(DCM_SeriesInstanceUID, "");

	        scu.sendFINDRequest(presID, &newDataSet, &findResponses);  //here will take a lot of time
            ......

		} 
		response++;
	} 

Code: Select all

scu.sendFINDRequest(presID, &newDataSet, &findResponses);  //here will take a lot of time

If you want to understand the relationship about query root and query level, you can see "testFindRequestList function" in dcmtk-3.6.0/dcmqrdb/libsrc/dcmqrdbi.cc

Thank you very much!
