storescp and negotiating transfer syntaxes

[vedicveko]

Hello,

I've been working with storescp using the provided storescp.cfg file trying to negotiate transfer syntaxes. I have read asconfig.txt but I'm afraid I'm too dense to really understand it in regards to what I'm trying to do.

What I would like to do is that on a per modality basis, negotiate a transfer syntax that I prefer and if the preferred transfer syntax is unavailable, fall back to something else. As an example, for a CT I would like to receive it in 'JPEGLossless:Non-hierarchical-1stOrderPrediction', if the sender isn't capable of this, fall back to 'LocalEndianExplicit.'

If you could shed some light on how I could do this, or even an example, I would greatly appreciate it.

As far as I remember, the order of transfer syntaxes defined for a certain presentation context is significant. In other words, the storescp (when used with a configuration file) prefers the first transfer syntax of a presentation context that matches the SCU's proposal.

Code: Select all

[[TransferSyntaxes]]

[Uncompressed]
TransferSyntax1 = LocalEndianExplicit
TransferSyntax2 = OppositeEndianExplicit
TransferSyntax3 = LittleEndianImplicit

[PreferredTransferSyntaxes]
# the first one is preferred (if offered by the SCU)
TransferSyntax1 = JPEGLossless:Non-hierarchical-1stOrderPrediction
TransferSyntax2 = LocalEndianExplicit
TransferSyntax3 = LittleEndianImplicit

[[PresentationContexts]]

[MyStorageSCP]
PresentationContext1 = VerificationSOPClass\Uncompressed
PresentationContext2 = CTImageStorage\PreferredTransferSyntaxes

[[Profiles]]

[MyProfile]
PresentationContexts = MyStorageSCP

Please note that I haven't tested the above configuration.
