Has anyone developed or is interested in developing a CC DICOM Silverlight Viewer? I've seen a few posts about it being on the roadmap but haven't seen anything further.
Thoughts? |

I am starting a Flex Viewer (Flash) using Adobe FlexBuilder based of the CC ImageViewer Framework... JUST the VIEWER/Render part.
Dont know much about SilverLight... is the a Drawing API for silverlight, like GDI or something? |

I am basically writing ActionScript 3 Classes for the CC ImageViewer Parts. Not that much Different in Syntax than C#. I am doing the PyhsicalSpace, ImageBox and Tiles classes now. then my Tile Class will be a Hybrid Object for the actual Image Processing.

Hi, a web viewer, potentially written in Silverlight, is on our radar. However, we have no solid timeline for this at the moment ... please stay tuned!
Best regards,

Hi Cliff,
No, not yet, I'm afraid.

Hello,
we have already done it. you can see a demo at :
www.e-stellar.com
login : demo@novealis.com
pass : demo
there is some function like windowing available with the left button, move with center button, right button to change of image...
(a help window is available, it is called, in French : aide)
for odd browser, like firefox, safari, we have add some key, because the middle en right button are badly managed in these browser.
We are still improving the viewer, and plan to add function like MPR MIP...
Best regards,
Olivier Robin

Olivier,
I took a look at the demo, and it looks nice! I'm curious, what back-end are you using with the silverlight viewer? Are you using our software in any way, or is it all your own software?
Thanks,
Steve |

Olivier,
Is that viewer available in English? Is that an open source viewer as well?
Thanks,
Cliff |

Hello,
I will try to answer to several question :o)
Our Viewer will be soon in English. if it is just for test, I can made an English explanation of what is what on the screen.
Why it will be soon in Englis ? because we start to have some demand for English Customers.
Our viewer is not free for the moment, and is not open source.
we plan to build soon a free version, with limited function (in fact, what you can see in the demo today).
it should be done when we will have done our new function, like Mip MPR, export to jpeg, import, etc...
Why it is not open source ?
because our company have build a special system, with a pacs, Web viewer, an archive system, etc....
our pacs have some spécial features, not found in the PACS you can find today, but this topic would not be the right place to discuss about that.
We are actually using some dll from ClearCanvas.
let me explain very quickly how it works :
The communication on the server side is done with our code.
we just have some look of how Clearcanvas do some job, just to help us to understand how it works.
so the Dicom communication is not from clearcanvas.
The Dicom file management (load, uncompress, find the TAG) is done by ClearCanvas dll : Clearcanvad.codec.rle, clearcanvas.codec etc...
We need that, because managing so many image format is a long process that we don't want ot investigate.
The client, in silverlight, ask for an image, a study, a serie, to the server.
the server ask to the pacs an image, by a query retreive, on directly in the database, if the pacs is our pacs.
the server un comress the files, manage the tag, compress everything in a special format, and send it to the client.
the client receive tags and pixel datas, in a compressed object.
then, I uncompress everything , I construct a silverlight image, and have done some méthod to calculate the windowing, the Hounsfield conversion, to manage all image format : gray, RGB, YUV, 8bits, 16 bits, etc...
it is just to explain quickly the things, and to be honest, it is not so complex finally than it can look like :o)
Best regards,
Olivier

Looks very nice. So is the image shown to the client a true, raw dicom file or is it a bitmap (jpeg, png, etc)? Do you experience a quality loss in the image? |

Hello,
Yes, it is true dicom image, shown on the silverlight component. I use silverlight 3, and the writable image component.
our firtsgoal id : no loss, and same quality in wondowing, center than "professionnal" viewer, like you can find in hospital.
second goal : something quite beautifull to see, and something easy to use.
Thank you.

Hi Mackey,
How are you going with the Flash project? I'm trying to do something similar and would like to get some advice from you regarding your re-write of the physical workspace, imagebox and tiles clases.
Regards,
DM |

Hey Oliver, to display the dicom image on a silverlight component, did you write a custom renderer for this?
We are investigating the possibility to use ClearCanvas to display dicom in WPF using C#, but are looking for the best solution for doing so! We have managed to use the DrawToBitmap function to make a bitmap of the image, but are now looking into creating a custom renderer for displaying the image on a WPF control!
Any guidelines from your implementation are more than welcome..
Thanks |

Hello,
I write the result of the windowing (the last step in my case) of the picture, in a buffer type : byte[]. each pixel is in the ARGB format (Alpha, Red, Green, Blue)
then, I link this buffer to a Writablebitmap (available in silverlight 3
this WritableBitmap is linked with a Image.Source

Olivier,
Would you be willing to sell the source code?

First of all, hi everybody.
My name is Emilien, and I am a new employee in the company Novealis, that developed the silverlight DICOM viewer that you can see here http://www.youtube.com/watch?v=IhpMjbUp70E (now with MPR, annotation and screenshot).
I replace Olivier as manager of this product. I am an IT engineer, working in C#/C++/Java in medical field, emphasis Medical Image processing.
You can still test the software here http://www.e-stellar.com/ (username: demo@novealis.com password: demo). A new version will be available in a few weeks allowing KEY IMAGES selection and MIP reconstruction.
Currently, Novealis has not the project to sell its code. Still, if you want some help on code samples, or if you are wondering how we manage some parts of the DICOM files, I can try to explain it shortly.
For people interesting, I will keep this topic up to date with our last version of the software, to let you know what we are able to do with Silverlight.
Unfortunately the software is still in French, because we have currently no english customers, and our priroity is on function implementation intsead of translation at the moment. Anyway, if there is something on the software that you don't understand because of the language, I will be happy to translate it for you!
Best regards,
Emilien

Emilien,
Just out of curiosity, are you doing server side or client side rendering with your web viewer? And, if you're doing client side rendering, are you supporting decompression of any DICOM transfer syntaxes in the client, or must you have uncompressed data? I'm just curious as to how you put things together.
