Hi. I'm implementing a Query/Retrieve system for teleradiology that
retrieves the PACS for studies and send them to another system.
The problem is that sometimes, when the query is performed, not all
the images are available for that study, therefore, not all images are
sent.
Is there any method that I can use to guarantee that the study is
complete in the PACS? Is this configurable in the context of the Query/
Retrieve? I know that some PACSs can "lock" the study until the end of
the storage (by timeout or storage commitment).

Can anyone help me?

If the PACS supports IHE Transaction RAD-49: Instance Availability
Notification (s. IHE Technical Framework, vol. III, available from
http://static.ihe.net/Technical_Framework/index.cfm ), the PACS can be
configured to notify your QR client via DICOM Instance Availability
Notification Service N-CREATE, when ALL instances created in ONE
Performed Procedure Step at the modality are available by Q/R at the
archive. But if the Requested Procedure is performed in several
Procedure Steps, also several Instance Availability Notifications -
one for each MPPS - will be sent to your QR client for one Study!

By the way, a Storage Commitment request from the modality does not
indicate, that all images of a study were transmitted !

Thanks for your fast reply, Gunter.

I'll keep that suggestion for future implementations.
However, and as you mentioned, I do not know in advance how many
Procedure Steps will be, and I am sure that it can be more than one.
Is there another way to acomplish what I want?

And by the way, where do I have to look to get these kind of answers.
Is the IHE Technical Framework the correct source?
