Hi Steve,

All the rendering is performed client side (windowing, reconstruction and so on...). But we are not supported decompression of any DICOM transfer syntaxes, we totally need the uncompressed data.

And it is actually a quite good question, because as you can see on the demo site, we need a few time to load all the images, that can become quite long in case of bad connection.

I am currently working on this optimisation phase, first by using a unique DICOM lossless compressed format (from our PACS solution) that I will manage client side, and then by managing any DICOM formats.

Thanks to this work, there will be less transfer between server and client to obtain the images.

Emilien,

We've done some investigation of the possibilities with Silverlight, and really didn't see any support for decompression, so I was curious as to how you were doing things.

Another final followup then, would be are you using the ClearCanvas libraries in any way for this project?

Steve

Well,

I just started the investigation to manage the decompression client side. If I found no way to do it properly in SL4, I will work on other solution to improve the data transfer.But note that in a first time, I will work on a unique compressed format, and it will very simplify my problem.

We used the CC libraries when this project started, to simplify our first implementation. But since we have developed our own C# DICOM manager.

This is why I still post on this forum to let you know how the project progress, without your great library, we were not able to have these results very quick. And also, even if I can not show the code, I hope to be able to help some people working on the same field.

Thus, thank you.

Emilien

Sorry just seen your post, reply done on your email adress!

LEADTOOLS has a Silverlight toolkit with native support for lots of formats so you don't have to use a conversion service to make the images JPEG or PNG first. It has full support for DICOM Data Sets so you can load and modify all of the tags as well as process and window-level the images.

Here's a link for information on the toolkit (and a free eval download):

Hi all,

for those wanting an open source starting point for a silverlight viewer

check out  https://github.com/cureos/mdcm this is a silverlight/WPF focused branch of the original mdcm project https://github.com/rcd/mdcm

from what I've seen CC uses a lot of the mcdm code. The author note's certain limitations on codecs.

Just an FYI for anyone following this thread who is not aware - CC has a complete Silverlight viewer as well that is currently part of the ImageServer. It has only been released as part of our Team Edition, but it is in the open source repository and is fully functional.
