We have used X-Rays as a medical imaging technique since approximately 1895 when Wilhelm Roentgen discovered that he was able to create images of internal bodily structures such as bones and tissues by passing electromagnetic waves through the body. He named the phenomenon "X" because he did not fully understand what made up the "rays". Since that time, X-Rays have been the building block upon which medical imaging technology and equipment for medical imaging have been built.
Although the X-Ray (or radiograph) has long been a fundamental medical imaging tool, this approach has always had the down side that the images produced are not exact. The images require extremely careful analysis and interpretation. Scientists have been researching for years in an attempt to find a way to make the radiographic images better.
