Send 1 image per associatino

Post by rhosenfeld » Tue Oct 11, 2005 3:16 pm

If I have a modality auto route it seems to send 1 image per dicom assoc as I can see in the log file. This works well and is pretty fast.

If I forward an entire study it is much slow and doesn't close the association until the end of the exam. Is there a way to modify this to send per image?

Based on our experience, it is actually much slower if PacsOne sends one image per association instead of sending all images of the study in the same association, because to establish each association, both entities (sender and receiver) must negotiate the association parameters (e.g., who's the sender, who's the receiver, the class and transfer syntax of the images being transferred, etc.). If PacsOne establishes one association per image, it has to perform the negotiation for each association for each image, which will take a lot longer versus using a single association (only a single negotiation is necessary).

The fact the automatically routed images may appear to be transferred faster is because the images are being transferred in parallel instead of sequentially (one by one) as in the case of forwarding a study.

If you want the forwarded study transferred faster, you can forward all series within the study (instead of forwarding the single study) by clicking on the Check All button to select all series of the study, so that each series of the study may be transferred using a separate association, thus achieving similar parallelism as the auto-routed images.

Thanks for the reply. I agree it is quicker to send by exam when on a 100 meg LAN. However, we're sending over 3meg and it seems quicker when sending by image. Thanks for any feedback.
