We have used X-Rays as a medical imaging technique since 1895 when Wilhelm Roentgen discovered that he was able to create photos of body structures like tissues and bones by putting electromagnetic waves through the body. He named the phenomenon �X� because he did not initially understand the composition of the �rays�. From that time forward, X-Rays have been the building block upon which medical imaging technology and equipment for medical imaging have been created.
Although the X-Ray has been an essential tool for medical imaging, this approach has had the down side that the photos made are not exact. The images require extremely careful study and interpretation. Scientists have long searched for a way to enhance the quality of radiographic images.
Recent discoveries in the growth of laser X-Ray's have led to advancements that have the ability to change the quality of radiographic images. The light generated by a laser would be bright enough to create strong, distinct contrasts on radiographic images. Moreover, grouping the candle power of a laser beam with X-Rays can produce better images by a factor of around 1,000. Medical imaging at this level of resolution could provide the technology to detect cancers and other abnormalities that cannot now be detected with current X-Ray technology.
Up until recently, the power source required to create the appropriate strength laser beam for this invention was so massive that it was impractical to even try. However, because of new techniques, researchers at the University of Colorado in Boulder have developed a way to create powerful laser beams from a reasonably sized source of power. This makes laser X-Ray technology a reachable goal.
The research team used a laser beam to send out atoms from argon. Argon is a stable chemical element. The emission of X-Rays was not strong enough to be of use. The research group then hurled the atoms back into the argon, causing a larger, more agreeable stream of X-Rays of big enough size to be of use. This �boomerang� technique is being handled to make a regular, very powerful source of X-Rays, grouped with laser beams.

No, this is not fiction. The story I've just told you—albeit with a bit of dramatic . on light elements and the X-rays identifying heavier elements.

The technique is not yet prepared for use in the clinical setting. More examining is needed to extend the technique into the hard X-Ray area of the electromagnetic spectrum. When the task at hand has been overcome, the commercial laser X-Ray will come next.
