When is a study send from the gateway to the OnepacsWeb?

[hilario]

ON the OnePacsWeb we have a counter (per facility) where we can change the time onepacs as to wait before considering the last image has arrived.
What happend on the gateway? Does it wait for the last image to begin to send it to OnePacsCentral?
Or does it begin to send images to OnePacsCentral as soon as it get some images?
Is there a counter on the gateway with the same functions than the previous counter on OnePacsWeb?
Thanks

Hilario,

The Gateway does not operate on a timer. It will begin sending images to the central server when one of two events happen:

1) The association terminates (either cleanly or unexpectedly)
2) The series context in the association changes (your SCU finishes sending one series and begins sending another).

It will only send images it receives in that session. For example, consider a 100 image study with 5, 20-image series. If the images are sent in a single association sequentially:

Image 21 received -> Gateway sends images 1 - 20, in one association
Image 41 received -> Gateway sends images 21 - 40, in another association
Image 61 received -> Gateway sends images 41 - 60, in another association
...

If the study is a single series with 100 images it will not begin sending until the C-STORE completes:

Image 100 is received -> Gateway sends images 1-100 in a single association

Hope this helps clarify things.

Thanks,

Justin
