X-rays create a collage of overlapping tissue layers, making it challenging to interpret 3D information from a 2D image.

“nothing in the body is two-dimensional so you talked about how this photon is going through the body and if it hits her rib well that's gonna show up as white whereas if it's passing through the lung between the ribs it's gonna show up as black but of course you could hit a rib on the front but not on the back you can hit a rib on the back and not on the front you can hit the sternum so when you look at an x-ray even to this day I'm still constantly amazed at what the collage looks like of overlapping layers of tissue”
