“X-rays were discovered in 1895 by Wilhelm Roentgen, a professor who was working on emissions from electric currents in a vacuum. As he worked, he discovered a glow coming from the barium platinocyanide-coated screen. He continued to experiment and was awarded the first Nobel Prize for physics in 1901” (Bansal, 2006). Many improvements have been made to Roentgen's discovery over the years, and radiography is available in hospitals around the world. Many different types of imaging can be performed today. These include fluoroscopy, CT scan, nuclear medicine and ultrasound. The significant use of fluoroscopy is that it intensifies the image during orthopedic, vascular and urological procedures. It is also used for dynamic radiographic investigations. “CT is useful for evaluating soft tissue involvement in injuries or determining the extent of fractures. In general, CT is useful for integrating anatomical or pathological information already obtained from conventional radiography” (Bontrager & Lampignano, 2010). “Nuclear medicine is more sensitive and generally provides earlier evidence than other modalities because it evaluates the physiological aspect rather than the anatomical aspect of these conditions. Nuclear medicine uses very small amounts of radioactive materials to diagnose and treat diseases” (Nuclear Medicine, 2013). “Ultrasound can be used in several ways, such as monitoring a fetus, diagnosing a condition, or guiding a surgeon during certain procedures using sound waves” (Ultrasound, 2011). A major change occurred with the development and common use of computer technology. “The use of a film-free radiology department has been very interesting for this medical sector. Digital radiography was introduced in the mid-1980s and now competes with screen radiography in all radiographic applications” (Bansal, 2006). X-rays are essentially used for the diagnosis of many different diseases and injuries. “They have many different advantages, such as low cost, mostly noninvasive nature, easy availability, relatively harmless, and fast imaging times. Putting all this together in a clear, perfectly contrasted image, it's no wonder why we use it” (Bansal, 2006). Film radiography is still used more commonly than digital radiography. “Although there is a decline in popularity of film x-ray, mainly because the potential for patient dose reduction is limited. Furthermore, unlike digital radiography, images cannot be contrast-edited once processed. In screen film radiography, the film is expensive, uses dangerous materials for processing, is very laborious, and long-term storage is difficult. Finally, film radiography is not compatible with image archiving and communication systems also known as PACS” (Bansal, 2006).
