What are X-ray tubes for?
Xray tubes create xrays used for emitting xray radiation, most commonly used for medical imaging.
What is the word xray in French?
Xrays are 'les rayons X' (used in the plural) in French.
Where and why do you use xrays?
You get an xray taken at a hosbital and it is used to see if you have a fractured or broken bone
How do they do thoracic inlet xrays?
A normal chest xray but angled up a little and a smaller area at the top of your chest.
Is the dose of radiation more or less than an xray?
Since xrays, themselves, are a form of radiation, the question makes no sense.
How do x rays see through things?
Xrays pass through most substinces. Various detectors can be used to detect the ammount of xrays that are sent from one side verses what is picked up on the other side. The difference can give you information about an object. Xray radiation is created when high speed electrons hit a solid object. Basically high voltage electricity (usually 40,000 - 120,00 volts) is pushed across a gap from a cathode to an anode. The Anode is usually made of tungsten or other materials that can withstand high temperatures. The anode is usually spinning so that the target is not hit in the same spot over and over again, this allows the anode to last longer. When the high voltage hits the target it releases xray radiation. Xray radiation is invisible, but it causes some elements to glow. The best used today are rare earth elements like yttrium and gadolinium. The xrays travel through the patient's body and hit a film cassette that is treated with some of these rare earth elements and it glows wherever the xrays reach it. Some of your body blocks the xrays so the screen only glows in areas that is not entirely blocked. The thicker and more dense the body part the more xrays are blocked. Bone is very dense so it blocks more xrays than most any other tissue, so bones show up as clear areas on the film. The film is placed between these screens inside the cassette safe from regular light. So that the only light that reaches this film is the light created by the glowing elements bombarded by xray radiation. The glowing of the elements bombarded by xrays causes the film to turn black and or grey depending on the amount of xrays that are blocked. Modern xray machines have cassettes that use different phosphorus materials that keep a temporary image on the cassette then the cassette is read by a machine and creates a digital image. There is no film in these type of cassettes. This is done because more and more facilities are not using film anymore. Storing xrays is cheaper and more efficient on computer hard drives as digital xrays. Because of the digital storage of xrays some xray machines do not use cassettes at all, only digital readers.
What if you see black areas on a bone Xray?
areas which are less dense and have allowed more xrays to pass through. eg Black = air, softer tissues. White= bone/ calcification
What is a starlike object that gives off enormous amounts of radio waves and xrays?
star like a sun big but not really starlike and xray gives off radio waves ......
Where online could one go to view broken foot xray's?
The website "Xraysgalore" is a popular site people go online to look at xrays of various different body parts in various states. One could easily view a broken foot xray on xraysgalore.
What is the antonym for xray?
There is no antonym. An xray is a wavelength. There is no opposite.
Total filtration for an xray beam is 2.5mm of lead or aluminum?
Aluminium
Why is it that sometimes when bones are x rayed they appear as white images?
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.
