Hi Frederic,

Have a look at 3D Object counter on http://imagejdocu.tudor.lu/doku.php?id=plugin:analysis:3d_object_counter:start
Once installed, you have 2 entries within the 3D OC section under  
plugins. Open the 2 images, the mask and the image to analyze. Have a  
look at the "Set measurements" entry and under "redirect to" select  
the image to analyze. Close "Set Measurements". Now select the mask,  
be sure that your image is well calibrated (if not, use Image/
Properties to do that) and launch the "3D Object counter" plugin. In  
the result window, you will have access to the volume.

I hope this is what you've been looking for.

Fabrice
