An X-ray machine is used to take pictures of your bones. It takes pictures to show if you have a fracture of abnormal problem in your bones. It can also detect pneumonia in the lungs. It looks scary when you first see it because it's so massive. You have to lay on a table under the part of the machine that actually takes the X-ray. It has a light that shines on the table you lay on, and whatever part of your body is under that light will be in the X-ray. To prevent a part of your body in the light from being in the X-ray, you need to wear a LED shield. While you're laying on the table waiting for your X-ray to be taken, the technician will take your X-ray in separate room. Then, the technician will develop your X-ray and give it to either you or your physician.
