If X-rays are not visible to the human eye, how can we see a doctors X-ray if our bones?

X-ray machines produce a stream of electromagnetic radiation that interacts with an anode in an x-ray tube. The x-rays made by this interaction are then directed toward the part of the body being examined.

Because of the machine being used. we can't see through the human eye because we're not able to because of all of the skin covering up.
