Invalid Presentation context

[sivasankari]

Hi all,

I have a test case to test the functions of Query and Retrieve, worklist , storage and print.
I am using findscu of dcmtk for sending query for both worklist and Query/Retrieve.

SCPs used for worklist and Q/R are wlmscpfs and imagectn respectively

When i send query through findscu to imagectn, test case passed and i am able to retrieve the response files in my directory.
Subsequently when i send worklist query to the wlmscpfs through findscu, test case is failing and get the following statements on the SCP
But Q/R test passing 'n' number of times.

"Association Received (cactus:FINDSCU -> OFFIS)

Association Acknowledged (Max Send PDV: 16372)

(but no valid presentation contexts)

Association Aborted

+++++++++++++++++++++++++++++

Association Received (cactus: -> )

Refusing Association (bad application context)"

But the worklist test is passing 'n' no. of times unless findscu is not used for Q/R.

why the presentation context becomes invalid when i test worklist after testing Q/R?
what could be the reason for worklist to fail?
Am i proceeding wrongly ,i mean, am i correct logically?

Thanks in advance,
shankari

When using FindSCU against a Worklist SCP, make sure you select the correct query model (--worklist).
