Hi,

First off I'm totally new to DICOM.

I'm using the DICOM toolkit to implement a SCP receiver.

I get this error message

Unable to find matching negotiated presentation context for sop Digital Mammography X-Ray Image Storage – For Presentation and syntax JPEG 2000 Image Compression (Lossless Only)

Am I missing some DDLs or there's a new DICOM toolkit that solves this problem.

Thanks!

Joe

Hi Joe,

Sorry, we do not support JPEG 2000 compressed images at the moment. We originally had a JPEG 2000 codec built using an open source toolkit, but there turned out to be a bug in the toolkit that causes image corruption, and so we had to remove it from release. We do have a JPEG 2000 codec built using a proprietary toolkit which we intend to make available as a paid-for plugin. If you want more information on this option, please contact us directly (see Contact Us at the top of this page).

Thanks Jasper,

I'll bring it up, but we have licensed Lead Tools, so I'm not sure the pay option
would fly ;-)

Regards,

Joe

Hi Joe,

The original codec using the open source toolkit is still available in the source tree for reference (and really in case the bug ever gets fixed and we can release the codec again). It shouldn't take much to, say, modify it to use a different toolkit :-)

Thanks Jasper,

I'll give a shot, because
I did a test with LeadTools SCP it worked but it took 8 minutes & 4 sec forr 1300 images. Not acceptable at all.

Hi Joe, you're just implementing the receiver side, right? Do you actually need to be able to decompress the images that you receive? If not, you can just add the correct Presentation Contexts in your SCP implementation so that you can receive J2K images. This is exactly what our ImageServer does - it doesn't have to have a matching codec for each Transfer Syntax.

Hope this helps,
Stewart

Thanks Stewart,

I'll try it as soon as I figure it out how to do it ;-)

Hi Stewart,

It's working. Here is what did to make work. I hope it will help someone.
pcid = assoc.AddPresentationContext(SopClass.DigitalMammographyXRayImageStorageForPresentation);
assoc.AddTransferSyntax(pcid, TransferSyntax.ExplicitVrLittleEndian);
assoc.AddTransferSyntax(pcid, TransferSyntax.ImplicitVrLittleEndian);
assoc.AddTransferSyntax(pcid, TransferSyntax.Jpeg2000ImageCompressionLosslessOnly);

Thanks!
