ImageJA now works as dicom viewer applet!

marcelvanherk · Apr 18th 2011

Finally I got it working (it works in chrome, not in IE for me) ! But you have to have the Java JRE installed. This viewer shows one image at a time.

This goes into the dicom.ini in cgi-bin:

Code

[webdefaults]size     = 560dsize    = 0compress = uniconsize = 48graphic  = gifviewer   = imagejaviewer[imagejaviewer]source   = imagejaviewer.cq

This is in imagejaviewer.cq:

Give it a try!

Hi,

With the very kind help of the ImageJ maintainer, Wayne Rasband, we are almost there. Just a few weeks patience for a new ImageJA release! Then imageJ can load stacks directly from the server web pages with a simple script. And now: see below the result!

marcelvanherk · Apr 26th 2011

This viewer loads the selected series as a stack in IMAGEJA (version 1.45f or newer required!). Please play with it. If you can code macros for ImageJ, you can undoubtedly make this viewer lots of other nice things.

This goes into the file dicom.ini in cgi-bin

Code

viewer   = imagejaviewer[imagejaviewer]source   = imagejaviewer.cq

This is new file imagejaviewer.cq that also goes into cgi-bin

I believe I already posted a response here, can't remember...

I'm getting a connection refused when enabling the javiewer.....any ideas?

Many thanks,

Robby

marcelvanherk · Feb 12th 2013

Hi Robbster,

the last time I tried it worked fine. Which software gives 'connection refused.? You should see come conquest info, imageJA and slider and buttons. Maybe try another browser (firefox)?

Marcel

Robbster · Feb 12th 2013

In my Apache error log I'm getting

[Tue Feb 12 17:27:31 2013] [error] [client xx.xx.xx.xx] script not found or unable to stat: /var/www/cgi-bin/StartupMacros.txt

Not sure what StartupMacros.txt is suppsed to be.

The java error I'm still getting is: <Error: java.net.ConnectException: Connection timed out: connect>

Thanks in advance!

Do I need to have an entry in the Known DICOM providers on the Conquest server? I wouldn't think I would need to get images from my web server. If I have the viewer= serversideviewer it works fine.

I have made the following changes only.

[webdefaults]
viewer = imagejaviewer
#viewer = aiviewer

[imagejaviewer]
source = ../scans/imagejaviewer.cq

Robbster · Feb 12th 2013

When the applet tries to load. It never gets as far as loading any images.

marcelvanherk · Feb 13th 2013

Hi,

You dicom.ini looks fine.

if the applet does not load, java may not be enabled. Try another browser?

Marcel

marcelvanherk · Feb 13th 2013

hi,

startupMacros.txt is an optional config file of ImageJAviewer. Should be no problem. I will test the stuff again tonight.

Marcel

Robbster · Feb 13th 2013

Unfortunately, or fortunately, I have tried IE, Firefox and Chrome. The applet still loads, and I still get the Connection refused java error. I see the buttons within the applet, its just that none of the images ever get loaded.

Many thanks again!

Robby

marcelvanherk · Feb 14th 2013

Hi,

Look into the viewer page source with your browser and see that the image references listed have correct URL's. I believe they are generated using webscriptaddress which needs to be set correctly in the dicom.ini in cgi-bin.

Still getting ClassNotFoundException

I'm sorry Marcel, I think I posted the source for using aiviewer. I was working with both to see if either would work.

marcelvanherk · Feb 14th 2013

Hi this is indeed AiViewer, you have to make sure

htdocs/dicomviewer100/dicomviewer

And this is also strange:

http://192.168.16.51/cgi-bin/d…5678&address=192.168.16.6

refers to two IP different addresses! So your config must be wrong (webscriptadress and webhost)

192.168.16.51 is my Apache server running in a linux VM

192.168.16.6 is my Conquest server running on Windows.

marcelvanherk · Feb 16th 2013

Hm,

does you apache have all the dgate stuff in cgi-bin?

try otherwise XAMPP to be sure.

Hi Marcel
I like to use ImageJA as webviewer. Have installed the hole thing and it works. Just have a little problem, he doesn`t show the patientname in the picture. How can I chage this? And an other thing, can I change the size of the pictures when he shows them the first time.
Thanks for your help.

Roelof

marcelvanherk · Aug 16th 2013

Hi Roelof,

I have really no idea, but if you look into file imagejaviewer.cq you will see it runs a script command like this:

document.ImageJA.eval('run("Stack From List...", "....")');

I am sure you can add any ImageJ script command there that you like.

Marcel
