looks at the air-filled cavities (sinuses) around the nose and
eyes. are a form of radiation, like light or radio waves, that
are focused into a beam, much like a flashlight beam. X-rays can
pass through most objects, including the human body. X-rays make
a picture by striking a detector that either exposes a film or
