[vladtaltos]

radon transform is used to produce tomography images. just take a look at the wikipedia page... s/he's talking about that...

[dfc → vladtaltos]

I guess(??) I could have been clearer.

I understand what tomography is. I am curious how to interpret the three images and the differences. What does this page demonstrate to the reader? To me they look almost exactly the same. The one big difference is that the original has the the intersecting arrows. (I am also not really sure what the arrows are supposed to convey.)

[hbar → dfc]

It's a simulation showing how 1% FP error doesn't have much effect on the result. They look almost the same...that's the point.

If you don't know what the arrows represent then you maybe don't understand what tomography is after all.
