No idea, sorry. I have never worked with x-ray experiments, but I guess it 
should theoretically be possible to get the 3D density. If you can obtain 
the density values in a 2D grid, maybe you can combine several planes to 
get a 3D grid...

The images I've shown are from theoretical calculations, and the software 
already outputs a 3D-grid of density data, all that's needed is a format 
conversion.
