In C-Move request in which order the images are retrieved ?

I have been looking in Dicom Standard, but I hadn't found anything
about my doubt.
My doubt is when I send to the PACS a C-MOVE request of a study, in
which order are the images retrieved ?

For example If i retrieve a study from de PACS, in which order the
images will be sent to me ? The order in images are retrieved is the
same that as they were stored in the PACS ? Or if I retrieve all the
images of study firts I will receive the images of the first series,
then the images of the second series, then the images of the third
series, ...

We would like to retrieve the images of study sort by series, to know
when a series of the retrieving study is retrieved.

Thanks

I don't believe the DICOM standard addresses which composites are
transferred first, second, etc. I believe its implementation specific
and most likely tied to the order returned by the implementation's
underlying database provider.

Two methods come to mind - doubtless others have other methods:

1) Keep track of the study-instance-uid and all the
series-instance-uids from the C-FIND or some other mechanism.

Then, issue a C-MOVE for each series-instance-uid, giving the Move-level
of "SERIES" and the study-instance-uid and series-instance-uid. This
will move the SERIES to the specified destination.

I believe KPACS does this.

2) Issue the C-MOVE at the "STUDY" level and specify the
study-instance-uid. This will move all the instances at once, so you'll
have to hash-out / sort the incoming composites in your Store SCP
according to series-instance-uid.

I agree with Chuck that the order is in general implementation
specific.

Our system supports however the option to perform the C-MOVE sorted by
Series Number (0020, 0011) and Instance Number (0020, 0013). Most of
the time this will get the images reasonable sorted to the destination
when doing a Patient or Study level C-MOVE.

Thanks for your help,

One question Victor which system are you using, to support C-MOVE
sorted by Series Number and Instance Number ?
