X-ray photons have higher energy than visible photons, so can go through things that visible photons can't, like flesh. But you need a detector on the other side to detect them, such as a photographic emulsion or Charge Coupled Device. I wouldn't think they could easily go through a brick wall though. A plasterboard wall, maybe.
