This example puts a nanoCT scan into perspective, as the 550 nm resolution allows a field of view of up to about 1 mm, allowing the tip of a toothpick for example to be analyzed in full 3D. This is why this is also called a 3D X-ray microscope. See below some images and videos of the internal structure (wood cell walls), including a wall thickness analysis.
