Yasser,
   Please don't email me directly with such questions unless we 
have previously established a dialog about it on the vtk-users
list.

You need to set your window and level:

       viewer->SetColorWindow(256);
       viewer->SetColorLevel(128);

The values you use will be dependent on your data; I used 256 & 128
as an example (with 8-bit unsigned monochrome pixels).

As for the medical example, I don't have one handy & I don't have
time to find one for you.  I suggest you try searching the archives
http://www.kitware.com/search.html   or try Google  http://www.google.com

Also, just keep trying to massage the medical example code -- it's all
there; you just have to tweak it.

HTH,
