Transferring dicom files over Internet

[martinrame]

I know this is not a dcmtk strictly related question, but I'm sure many of us, faced the issue of sending dicom files over the internet.

Part of my job is administering a Fuji Synapse PACS, apart from developing my own PACS, based on DCMTK. Over the time, I replicated many of Synapse's functionalities, but I can't find how can it get images so fast, even in long distance networks.

Do you know, apart from compressing images, another way or trick to improve the performance of network transfer? or, at least let the user think image transfer is fast?.

Thanks in advance,
Leonardo.

Intriguing. Can you give some more details of what kind of DICOM data you are sending, and what Synapse users see when they think the transfer is complete?

You could also try to look at a process viewer while receiving files, to see whether the bottleneck is the CPU (dcmtk issue), and whether the network interface is fully utilized (smart preview issue).

It'd be interesting to hear what you find out.
