Getting Ginkgo CADx up and running on Ubuntu

I needed to look at some MRT images but the CDs doctors provide you after your tube ride only contain a windows viewer. So when I clicked on the image data on the disc Ubuntu was recommending Ginkgo CADx to me, which I installed right away.

The first start was however a disappointment. I was able to see a thumbnail of the image but when clicking on it no image was opening an an error message was displayed.

The Ginkgo CADx web site was also of no help. It seems once upon a time a fix was described but now it is gone. By the way I am using version 2.6 of that program.

Starting the program from command line reveals an error about shared libraries that do not load properly. So in the end editing the .inf files in that directory to load the correct library files fixed the problem for me.

How to fix it

1. Cd to

2. Open up the .inf file in an editor with super user privileges:

3. Change the first line in each of the two files by basically just removing each time the trailing “.2.6.0.” as shown below and of course save the changes.

Start the program again and it should work. I recommend to start it from the command line.

Using Ginkgo CADx

The program is working nicely. Remember it is for free.

Open up the “dicomdat” folder of your CD data, click on the thumbnail to view the real images.

Zoom in and out by turning the mouse wheel.

Hold down the Ctrl key while turning the mouse wheel to flip movie like through the views.

Quite impressive is the 3DTool which combines a series of images taken from one angle into a 3D view. Just try it out.

I prefer to start this program from the command line as it will not exit properly. So issuing Ctrl-C will then exit the program brutally but effective.
