If the angle of incidence is equal to the angle of reflection, then how do X-rays show such sharp images of bones?

Question

If the rays hit the bone then reflect off, would they not travel at a diagonal and not directly back at the machine to make such an image?

Answer 1

Whether the x-rays bounce off or go through is not the point. You still have diagonal refractions or reflections.

The cartridges that hold the x-ray film (or digital receiver) have a grid on them that filters most of the diagonal x-rays out, which sharpens up the picture.
