How can one get a sharp picture of an X-rays radiography
 
Since X-rays have wavelengths about the order of the angstrom (same as atoms/molecules), shoudn't there be a lot of diffraction when they pass through bones? I would have expected to see something like http://upload.wikimedia.org/wikipedi...ern_3clpro.jpg instead of a sharp picture of bones.
I don't understand how it's possible to get a sharp picture of bones with medical x-rays.
Does someone has ideas?
