It is an xray that is taken by a computer. Normal x-rays are taken when X radiation passes through you body and reaches a x-ray cassette with film in it. The more dense areas of the body (bones) absorb the x radiation and keep them from hitting the film (called partial absorbtion) thus the bone are lighter white color. Areas such a lungs which have air in them are not as dense as bone and do not absorb x rays thus they are black on film. Other areas with densitys between bone and lung (air) will result in different levels of grays. The film is exposed by the xrays that are not absorbed and partly absorbed by the body. Also it is key to note the xray cassette that hold the film has a screen inside it that is emits a light when hit with xrays. It actually the screen lighting up that exposes the film, which in turn is developed into the traditional xray film. In digital xray there is no film. The xrays expose a photo cell that is connected to a computer. Thus connected to a display. The nice thing about a digital xray is you can adjust the black and gray levels and send the image over the internet to radiologists all over the world. Hope this helps. Do take note that digital x-ray always to be confused with the x-ray radiation as being 'digital'. The fact is only image acquisition is digital and there is so such thing as digital x radiation.

Who invented digital x-rays?
Christian Villarreal
What are three advantages of digital x-rays over film x-rays?
they are fast ,they are less expensive ,they use lower amount of radiation
What is used to detect gamma rays?
By X-ray film or some kind of detector that is the digital equivalent.
How does an x ray machine work?
Think of it as a camera (it used to be on film, but now its a digital picture) that uses X-rays instead of visable light. The most common way to produce X-rays is with a special vacume tube inside of which an electron beam strikes a metalic plate.
What are the effects of radioactive substances on x ray film?
X-rays will "expose" X-ray film. That's how imaging (medical or otherwise) is accomplished using X-rays. We know that X-rays are high energy electromagnetic rays, and they are a form of penetrating radiation. X-ray film is photographic film, and this is film which will undergo chemical changes when exposed to light. X-rays and visible (optical) light are both electromagnetic radiation, and exposing film to X-rays will "leave an image" on the film, depending on the conditions of exposure. When using X-rays, which have a great ability to penetrate different materials, we enclose the film in a "film pack" which is positioned in such a way that it is "behind" the subject or object to be X-rayed. The source emits the X-rays, they pass through the object under scrutiny, and through the film. (The film is shielded from optical light by the packaging, but the X-rays pass right through it.) The film, which has been exposed to the X-rays, is then developed to yield images. We might note that modern imaging is moving to a "digital" X-ray with the elimination of the film and the substitution of an X-ray sensitive "grid" or "screen" behind the subject. This makes images quickly available (there is no delay as with developing film) and allows for immediate digital storage (with no "conversion" from film to digital format).
X in space words?
X-Rays X-Rays from the sun
What is the plural of x-ray?
X-rays is the plural of x-ray
What is the difference between soft x-rays and hard x-rays?
Soft X-Rays have lower frequency and energy (125ev), than hard X-Rays,(125kev).
When was The X-Rays created?
The X-Rays was created in 1897.
Who reads x rays?
x rays the person who reads x rays is called a radiologist
Presence of black hole can be notify by the emission of ------- rays?
X-rays, mainly.
What is x rays and gamma rays?
Cathode rays generate x-rays and gamma rays are electromagnetic radiation. Gamma rays have very high penetration power.
