findscu -Key Attributes - nested tags

[Nico]

Hi All,

How can I modify a value for a nested tag while building the KEY Attribute for findscu ?

           keys.setString(Tag.QueryRetrieveLevel, VR.CS, "STUDY");          
           keys.setString(Tag.StudyInstanceUID, VR.UI);
           keys.setString(Tag.PatientName, VR.PN);
           keys.setString(Tag.PatientID, VR.LO);
           keys.setString(Tag.AccessionNumber,VR.SH);

The tag I want to modify is ScheduledProcedureStepStartDate like this "20060705-20190707"

I've tried this , but wont work since it is a nested tag   (Parent tag :ScheduledProcedureStepSequence)

keys.setString(Tag.ScheduledProcedureStepStartDate, VR.DA,"20060705-20190707");

I also tried the next lines, but they wont allow me to set date tag

           keys.ensureSequence(Tag.ScheduledProcedureStepSequence,0);
           keys.newSequence(Tag.ScheduledProcedureStepSequence,Tag.ScheduledProcedureStepStartDate);

Does anyone know how to setString for this nested tag? ScheduledProcedureStepStartDate

Regards,

Nicolás

You have to create separate dataset (tag object) for SPS Sequence and add it to Tag.ScheduledProcedureStepSequence object.

Hi Prakash Jayaraman,

I'm trying your suggestion.

Thank you!

Thank you  Prakash Jayaraman,

I tried your suggestion , like the following

Attributes keys = new Attributes();          

keys.setString(Tag.QueryRetrieveLevel, VR.CS, "STUDY");          
keys.setString(Tag.StudyInstanceUID, VR.UI);
keys.setString(Tag.PatientName, VR.PN);
keys.setString(Tag.PatientID, VR.LO);
keys.setString(Tag.AccessionNumber, VR.SH);



//
  Attributes  scheduledProcedure = new Attributes();//Building new dataset (nested tags)
  Sequence seq = keys.newSequence(Tag.ScheduledProcedureStepSequence, 0);//Building a sequence within the main dataset
  scheduledProcedure.setString(Tag.ScheduledProcedureStepStartDate, VR.DA, "20180516-20180516");//Modifying the a tag within the new dataset.
  seq.add(scheduledProcedure);//adding the new Dataset to the main dataset.



Result :

 

23:41:02,147 DEBUG - Dataset:
(0008,0050) SH [] AccessionNumber
(0008,0052) CS [STUDY] QueryRetrieveLevel
(0010,0010) PN [] PatientName
(0010,0020) LO [] PatientID
(0020,000D) UI [] StudyInstanceUID
(0040,0100) SQ [1 Items] ScheduledProcedureStepSequence
>Item #1
>(0040,0002) DA [20180516-20180516] ScheduledProcedureStepStartDate

Is this what you meant ? any suggestion ... is welcome.

Thank you again,

Yes, you are almost there. I think you have to set the sequence in to the key like keys.newSequence(Tag.ScheduledProcedureStepSequence, scheduledProcedure) - Here instead of values you will need to set sequence dataset. 

I haven't tested it. I'm telling this from my past MWL programming using dcm4che 2.x.

Hi Prakash Jayaraman,

I think you mean this :

Attributes  scheduledProcedure = new Attributes();

scheduledProcedure.setString(Tag.Modality, VR.CS);
keys.newSequence(Tag.ScheduledProcedureStepSequence,0).add(scheduledProcedure);

I was searching code examples in dcm4che-tools and weasis and I found this :

    private static void addReferencedPerformedProcedureStepSequence(String mppsiuid,
            StoreSCU storescu) {
        Attributes attrs = storescu.getAttributes();
        Sequence seq = attrs.newSequence(Tag.ReferencedPerformedProcedureStepSequence, 1);
        Attributes item = new Attributes(2);
        item.setString(Tag.ReferencedSOPClassUID, VR.UI, UID.ModalityPerformedProcedureStepSOPClass);
        item.setString(Tag.ReferencedSOPInstanceUID, VR.UI, mppsiuid);
        seq.add(item);
    }

I think I will stick to this way.

Nicolás

Now I'm facing an issue that I think I will post in a new  thread,

When I setString the PatientID tag with a value like 3000, dcm4chee pacs returns all the Worklist entries instead of the desired of just the desired one.

keys.setString(Tag.PatientID, VR.LO,"3000");        
keys.setString(Tag.PatientName, VR.PN);
keys.setString(Tag.AccessionNumber,VR.SH);

The Pacs returns :

(0008,0050) SH [223.1] AccessionNumber
(0010,0010) PN [SACH^MARTIN] PatientName
(0010,0020) LO [M4001] PatientID
-----------------------------
(0008,0050) SH [1189.2] AccessionNumber
(0010,0010) PN [BIACHELLA^MAXIMILIANO] PatientName
(0010,0020) LO [3000] PatientID

I am probably missing something.
