Hi,
here is code that uses DcmSCU and does the following:
Negotiating Verification (echo), as well as FIND (query) and MOVE (retrieve) SOP Classes with the PACS. Then, send ECHO, send FIND and retrieve all studies that were found within the FIND step by sending a MOVE for each study. Then, release the association.
Best regards,
Michael
