Imaging doesn't necessarily produce 'images' in the common meaning of the word.
You may think that those 'images' of proteins you see sometimes are 'real images', because they are grey and grainy, but they are just computer-generated diagrams.
I'm not really sure if this comment has any substance. What do you want/expect to see?
"have used a method called atomic-resolution electron tomography to determine the position of every atom in a nanometre-scale sample of a metallic glass" assuming the accompanying diagram is exactly that, it's as much of an image as you will ever get, of anything, afaic.
