Hello!
   
  I'm new in the list and this is my first message.
   
  I need help to reconstruct in 3D a burrow system that is inside of a rock. Yes, its a fossil. It is a complex network of interconected burrows. Burrows are not empty, they are filled with rock, but slightly different to the enclosing rock. So a difference of density is between rock and burrow sufficient for to be detected in a tomograph.
  I've scanned the sample in a conventional medical scanner and then, I have a lot of images of sections, spaced every 1 mm, of the sample.
   
  I need help for  
                          1) In every image to select atomatically the zones corresponding to burrows and then to eliminate the rest of the image; and
                         2) with the resulting series of images of "burrows sections" to make a three dimensional reconstruction of the burrow system.
   
  My computer skills have been exceeded when I tried to do it alone using ImageJ, in fact I never use any other images software than Photoshop or similar.
   
  If someone can help me or at least tell me if it is, or not, possible of make using ImageJ I will be very grateful.
   
  Also if someone know about other software that can help me, please let me know.
   
  Thanks to all of you
   
  Sincerely
