DICOM: Do we get "short" response when Simulating to be Origin System from command line to DICOM TCP Service, with respect to a classic DICOM Studio Service？？

Good morning,

First of all, thank you very much in advance for reading and responding.

Also, thank you for any support, because it is a relief, support, contribution, help to have people with more understanding, knowledge and practice, reading, and thinking this doubt.

There is the following need:

Two 2 circuits are available:

1st DICOM Circuit of "Studio" ( Classic Service ).

Service: class: DICOM.BS.QueryService

Process: class: DICOM.BP.QueryProcess

Operation: class: EnsLib.DICOM.Operation.TCP

We test from the "Console" of the "Studio" by means of:

do ##class(DICOM.BS.QueryService).TestFind("102030")

In the previous example, "102030" is the user's PatientID

The interesting thing here is the trace:

On a visual level:

We observe the following information in the request which we send to Destination System, in the DICOM.Document:

We receive a lot of content:

However, using the other circuit there are discrepancies:

2nd TCP DICOM circuit( It is tested by command line ).

Service: class: EnsLib.DICOM.Service.TCP

Process: class: DICOM.BP.QueryProcess

Operation: class: EnsLib.DICOM.Operation.TCP

To test this second circuit we execute the following line into a command line:

./findscu -b VNAPRE -c ESBPRE@10.XWZ.4.ABC:19XYZ -m PatientID="102030"

Being the visual trace for this 2nd circuit the following one:

Being the information sent to the target system by means of DICOM.Document:

Here comes the question:

Why does very little information come out in this response, being replied to the 2nd circuit?

In particular the trace at command line level is detailed here:

We note that there are 3 responses:

10:30:39.170 INFO - VNAPRE->ESBPRE(1) >> 1:C-FIND-RSP

10:30:39.175 INFO - VNAPRE->ESBPRE(1) >> 1:C-FIND-RSP

10:30:39.176 INFO - VNAPRE->ESBPRE(1) >> 1:C-FIND-RSP

However, why is there very little information in the response transmitted by the destination system?

Specifically, in the 1st circuit we get, some more interesting data as:

SpecificCharacterSet, StudyDate, StudyDescription, PatientName, StudyInstanceUID

Which are being spotted here:

While in the DICOM TCP, in the 2nd circuit:

We only get from the destination system the following data: QueryRetrieveLevel, RetrieveAETitle, PatientID

Which is being marked and spotted in the next picture:
