X ray Machines work by creating a beam of radiation that passes through an object (or body part) and hits a "film cassette. The radiation causes a reaction with the interior of the cassette and this reaction produces light which in turn exposes the xray film inside. The film is then developed to show the image.
The amount of energy the beam contains determines how much radiation will go through an object to hit the cassette. This energy level is determined by the person operating the machine and must be calibrated to the size and density of the object being viewed. The x rays will not penetrate dense objects as well as less dense ones, because of this the areas where the beam passed through dense bone will remain unexposed on the film.
To simplify, the x rays are not looking at your bone as much as they are looking at the difference in densities between the bones and the surrounding tissues.
No, x-rays, gamma rays, ultraviolet rays and microwave rays are not on our colour spectrum which is why we can't see them. Some animals can see ultraviolet rays. Humans are restricted to the colours of the rainbow - red, orange, yellow, green, blue, indigo and violet and all the shades in between.
Not without technology. Unless your Super-man.
No. They only see the bone. Not inside.
Not with the naked eye.
Usually to check for broken bones or bone malformations.
Bones and other solids, Why? Because their higher density stops more X-rays than soft tissues do.
No they cannot.
Xrays are high energy waves that can penetrate soft tissue, like organs and skin, but not bones and teeth. Therefore, when you stand in the xray machine, the film is exposed to xrays only where they can pass through the body. Hence, you get pictures of bones and teeth but not organs and skin.
Yes, that's why it is used to tell where bones are. The x-rays pass through the tissues like muscles and fat but are stopped by the bones.
no they do not have bones, just a big wormy body full of muscles.nnnnnnnnnnnnnnnnnnnnnnnnoooooooooooooooooooooooooooooooooooo ^actually this is incorrect. worms do in fact have bones thats why they show up on xrays looking like dragons
yeah because it can break the bones so wheb your next in hospital, do not get x-rayed
Xrays and CT scans
Yes you can very clearly and its just so amazing!
You get an xray taken at a hosbital and it is used to see if you have a fractured or broken bone
Bones always appear as white images in regular xrays. However they arent really white because the film is clear, the plastic on the view box is white. But on xray film it is coated with a metalic layer. The xrays make the metalic layer stick to the film. So the black part of the film is where all the xrays reach the film. If the area on the xray is gray, then that means that some of the xrays are getting through implying that the structure is more dense than the black part. Soft tissue appears gray. The bone is a very dense structure allowing minimal to no xrays getting through. The film is then put through the processor and the film runs through chemicals that make the picture "stay" on the film. It is then rinsed and dried. Since the xrays make the metalic layer stick, none stick to the area of the bone because no radiation got through and the layer was washed off during processing. This is why bones appear white, they are the densest structure.
Well if you're sick it can help the doctor diagnose you. You shouldn't go get xrays just for the fun of it. In fact doctors wont order xrays just cause you want to see them.
