Oviyam 2.0 - It's finally here!

[Suresh Viswanathan]

Hi All,

It's finally here - the first beta release of Oviyam 2.0, the HTML 5 successor to Oviyam. It's been re-written from ground up to take advantage of the advances in web technologies since the release of the original Oviyam. The old Oviyam codebase will continue to receive bug fixes but our developmental resources will be focused on Oviyam 2.0 going forward.

For the TL;DR crowd ones here's the download link:

Oviyam 2.0- Beta1 - Sourceforge.net - Download link

We're still working on cleaning the source code and would probably release it with the next beta. It's available on demand right now if you want to have a look. Use the latest versions of Safari or Chrome for optimal results. Support for other browsers will be added in future releases.

Features:

01. Login security (uses dcm4chee's authentication).

02. Multiple AE (server) configuration. 

03. Query by Patient Name, ID, Accession Number,Birth date, Study date, Study description, Referring physician or Modality.

04. Customisable Quick Query buttons (Eg: Today's CT, Morning X-ray, etc.)

05. Local storage & retrieval of images (browser dependent). Locally available studies are displayed with a green ball in the query result.

06. Thumbnail preview of the query result. 

07. Query auto refresh.

08. Open multiple patients in tabs.

09. Tools and features in the viewer: 

• Vertical & Horizontal flip. 
  
• Left and Right rotate. 
  
• Pan & Zoom.
  
• Zoom to fit screen.
  
• Invert. 
  
• Stack navigation of images on mouse drag 
  
• Reset image. 
  
• Text Overlay. 
  
• Tiled layout:
  
• Comparison of multiple series side by side
• Synchronised image scrolling of multiple series.
• Scout / localizer lines.  
• True 12 bit Window level / Window width adjustment. 
  
• Preset WL/WW values. 
  
• Display HU, X, Y values during WL/WW adjustment (512 x 512 CT & MRI images only).
  
• Full screen mode. 
  
• Display meta-data. 
  
• Measurement. 
  
• Cine loop,
• Display image orientation. 
  
• Change image orientation while horizontal/vertical flip. 
  
• View encapsulated PDF DICOM objects. 
  
• Context menu to change series. 
  
• Three different thumbnail series view options with current image indicator.
  
• Slider to change images. 
  

10. Viewer configuration and server settings can now only be changed by an administrator.

11. Session timeout for security.

12. Multiple themes.

13. Direct URL launch for EMR integration.

14. Multi-frame support is partially supported.

Hop you like what you see and have as much fun using it as we did creating it. Feedback, bug fix & feature requests are always welcome. 

Coming soon: iOviyam 2.0 for mobile devices with multi- touch support and Mayam 2.0

The Raster Images Team

[simonmd]

Awesome...we'll givet a spin.

[Robby Otts]

This looks awesome!  Exactly what I was looking for.  It's going back and querying data from my Conquest server.

Got it up and running in no time.  I'm getting all the way to the point to where it's trying to pull up images but it is never displaying them. The viewer is just "spinning" and never loads an image, either on the internal network or over the internet.

I'm thinking it might have something to do with my server setup?  I'm getting java.net.ConenctException: Connection timed out errors.

2013-02-14 11:44:02,931 ERROR -> (http-0.0.0.0-8080-19) [in.raster.oviyam5.servlet.DcmImage] Unable to read and write the image from http://192.168.16.6:8080

java.net.ConnectException: Connection timed out

192.168.16.6 is my remote Conquest Server.

[Suresh Viswanathan]

Unfortunately you've been hit by the lack of WADO service in Conquest. Oviyam uses WADO to retrieve images as JPEG images from the server. WADO generates JPEG images from the original DICOM image.

dcm4chee has a built-in WADO service. We're looking to add WADO as an optional part to Oviyam in a future release to support Conquest and ClearCanvas Image Server.

Suresh

[Robby Otts]

I have changed the WADO port from 8080 to 80 yet still no images.

I am not going thru a web server using dgate.  Is this necessary to get the images delivered?  I've also tried setting up Oviyam2 ha a "Known DICOM provider" in the Conquest server....tried port 80 and port 8080.....no results...

Any ideas?

Many thanks,

Robby

[Robby Otts]

I thought I had read that WADO serivce was added in 1.4.12.  We are now running 1.1.17alpha.

 

I was really hoping for this to be our solution.  I'm desperately running out of time with my client.  We thought dcm4chee would be the solution for web based viewing but it will not query Conquest directly.  Our clients are not willing to push images from Conquest into dcm4chee since we would have to maintain images in two places.

 

This Oviyam interface is really, really nice!

IIRC, Conquest does not have WADO. You can read more on this:

Web Access to DICOM Objects (WADO) Service

Web Access to DICOM Persistent Objects (WADO)

Suresh

[Suresh Viswanathan]

Oh, that's news to me. I made my earlier post before reading yours.  Make sure Conquest WADO can generate jpeg images. (fFor example, ClearCanvas ImageServer has WADO but it can be used only to query DICOM images) Have you been able to test it out by creating your own WADO URL? If you have  a programming background, you can look into the complexities of pulling out the WADO code from dcm4chee and adding it to Oviyam, provided you have the time.

Thanks for the compliment. It's still work in progress.

Suresh.

[Robby Otts]

I am by no means a developer....a linux/unix engineer.

I'm simply trying to get a web based viewer set up for a client to be used over the internet.  I have had absolutely no success up to this point.

[Jhon Carrillo]

 Any Idea about it?

[fleetwoodfc]

Conquest does advertise that it has WADO and I have been able to get it to work through the Conquest web pages (dgate application). However so far I have been unable to get it to work with other clients e.g. Oviyam or the CharruaSoft WADO Client.  

[fleetwoodfc]

Great work. Definitely going in the right direction.

Out testing so far has been only under JBoss. We'll be looking to add Tomcat support in future versions.

Hi,

I am working with JBoss according to the dcm4chee installation manual.

Cordially,

[ime]

First of all thank you for new version of oviyam 2.

I try oviyam 2 with dcm4chee 2.15.0 and cannot see two images from conquest server.

I send two ct images (which comes with conquest server) to dcm4chee. I can view images in dcm4chee, but i can't view in oviyam 2!

[Suresh Viswanathan]

Can you see it using dcm4chee-web? This is to verify if there is a WADO problem.

Suresh

[fabrizzi...@msn.com]

Excellent work , thanks.

when i try it with an ipad, the page is redirect to IVIEWER, but this file is not in the war. this is for a newer beta version??

Regards

[Suresh Viswanathan]

Hi Rob,

In our internal discussions for the next beta release, we've looked the possibility of adding an internal WADO like service which would allow Oviyam to be used with Conquest and ClearCanvas Image Server. Do you still have time with the client to wait for the next release?

Suresh

[Robby Otts]

Not sure. We're already weeks behind. However, they are using K-Pacs as a viewer internally and I've also true to get the seriesviewer2 setting to work in Conquest web which might work for now. Hopefully. 

Still having some issues getting it to work though

[chris...@web.de]

hi there,
thanks a lot for his awesome work! i really enjoy oviyam since the beginning...
as we do a lot of cardiac mri we always have large studies (up to 20000 images) and it takes too long to load them. could you add a feature just to load single sequences of one study? this would help a lot!
thanks
chris

[Suresh Viswanathan]

20,000? That's lot of images. I'll look into adding it as a configurable option.

Suresh

[chris...@web.de]

that would be great solution!
thanks in advance
chris

[Paolo Marcheschi]

Hi Suresh, How are you

This is a very interesting release.

I tried it and I must admit that It is very promising, I have tried CT and DR so far, and it works fine,
This is not for production use at the moment , I still prefer the Mayam feeling, This release is still buggy, I had to exit and re-enter several times in order to view images correctly.
Thank you For this work

Ciao

Paolo

[Suresh Viswanathan]

Thanks Paolo. Can you reproduce & document the bugs? It would help us to fix them.

Regards

Suresh

[Prakash Jayaraman]

Most of the functions of Oviyam 2.0 may not work with iPad, since it was not intended for tablet. iOviyam 2.0, mobile and tablet version of Oviyam 2.0 is on final testing and you expect its release shortly.

The invalid link "IVIEWER" will be removed in the next release.

Prakash.

[charles strickland]

I cannot get oviyam to work. Do I need to have anything other than a working dcm4chee? getting error The requested resource (/oviyam2) is not available.

[asgarhu...@raster.in]

Please try with http://hostname:port/Oviyam2.

If you want to use /oviyam2 then rename the war file and deploy it.

[Suresh Viswanathan]

Case is important in the URL. /Oviyam2 is different from /oviyam2

Suresh.

[charles strickland]

Brilliant. That was it. Never would have tried it. Thanks

[charles strickland]

Got oviyam setup, can query for studies. Images will not load, just spins "loading". I see the thumbnail placeholders but not thumbnails.

[asgarhu...@raster.in]

Are you able to see images in dcm4chee-web interface. 

Please attach error log, if possible.

[charles strickland]

Looks like I used 64bit java, will change to 32bit and see if that helps.

[charles strickland]

That was it. Working now.

[Suresh Viswanathan]

IIRC, Java 64 under Windows does not have JAI support which probably caused the problem you faced. Now that you have it working, how is it?

Suresh.

[charles strickland]

I am unable to load all series of Echo studies (US). Only 3 of 24 series shows in the viewer. Sometimes they play sometimes not. I can't seem to find a reason.

XA studies seem to work a lot better. The entire series loads. But when I am playing the loop and try to load the next series the viewer hangs. If I uncheck loop and going to next series it works fine. The loop checkbox seems to cause problems. If it is checked and you change layout it hangs.

I also would wish for a automatic setting for playback speed that would match the images. 15 fps in my scenario. Also would like playback for all series in multiple layout.

I like that a dicom pdf viewer is included. That works well. Image quality seems to be great, and playback of cine is great when the speed is adjusted.

[Suresh Viswanathan]

Any chance of sending the Echo & XA studies for testing? Dropbox or FTP would work.  Automatic playback setting is planned for in a future release. This is still the first beta release. There's still a lot of work to be done. 

Suresh.

Sure. I will get them uploaded to dropbox.

Hello Suresh,

Regarding your comment about ClearCanvas serving only Dicom images via Wado, I would suggest to use a web viewer supporting Dicom images.

In particular, I would point to medview [ https://github.com/jap1968/medview ], a just released html5 Dicom viewer, capable to connect to any pacs supporting c-find SCP

The viewer is still very limited and not ready for production use, but I think it could be interesting for anyone having a Dicom server and, in particular, for the users of ClearCanvas Pacs.

Hi José,

Thanks for the link. I'll have a look.

FYI, the latest release of Oviyam 2.0 (ß2) now supports ClearCanvas, Conquest or any archive that supports C-MOVE or C-GET. It still needs to be installed on a dcm4chee server - we plan on removing that dependency with the net release.

Suresh

[Douglas Cesconetto]

Guys, sorry for this silly question. I can't run Oviyam with dcm4chee , I'm following this instructions:

After copy the oviyam.war file to /var/lib/dcm4chee/server/default/deploy I have to something else?
I tried to access http://192.168.0.10:8080/oviyam from another computer but I had a 404 message.

I tried to refresh Jboss service too.

Please, help.

[Suresh Viswanathan]

Try http://192.168.0.10:8080/oviyam2

The last bit should be the same as the war file you deploy. The wiki instructions are for the earlier version.

Actually I tried the 0.9 and oviyam2 version, thats why I wrote ../oviyam but in both cases I had the same problem. I'm using dcm4chee installed on linux Ubuntu, I had installed using this live CD:

http://cdmedicpacsweb.sourceforge.net/LIVE_CD.html

It's already have the Weasis but it's not enough for me, oviyam seems to be much better and have a query/retrieve option. I can see in Jboss manager references of Weasis but nothing oviyam, I think I'm doing something wrong.

:-/

Please, help me.

[Jorge Millan]

Hi Suresh,

I came across your website looking for a web based Dicom viewer. Do you have installation instructions on how to install it in a web server?

Best regards

Jorge Millan

[Suresh Viswanathan]

It’s fairly straightforward, 

Step 1 - Install JBoss (preferable) or Tomcat

Step 2 - Deploy the Oviyam WAR file

Step 3 - Configure Oviyam to connect to your DICOM archive 

Suresh.
