Here is the lua code for a barebones WADO viewer as it runs from the conquest web server environmentr. It may be very easy to adjust to dwv. -- 20120302 mvh Created

Thanks for your interest, I'll give it a try as soon as I can in this busy period! |

I put the dwv.lua script in the resources folder. It contains explanations on how to use it. As does the wiki page Pacs support. |

Hi Yves, I posted a small update on the conquest forum to allow browsing the slices. Regards, Marcel Van: ivmartel [notifications@github.com] I put the dwv.luahttps://github.com/ivmartel/dwv/blob/master/resources/dwv.lua script in the resources folder. It contains explanations on how to use it. As does the wiki page Pacs supporthttps://github.com/ivmartel/dwv/wiki/Pacs-support. — |

Here is a link to the conquest forum thread: http://forum.image-systems.biz/viewtopic.php?f=33&t=17196 |
Hi,
I write and maintain the conquest DICOM server. It should be trivial to create a Conquest web viewer based on your work. The link below shows how I load ImageJA as viewer as an example. Could we together have a try to integrate yours?
