What would Wilhelm Roentgen, the father of X-rays, say about current technological discoveries in radiology? Since the introduction of X-rays in 1895, significant advances have revolutionized the field of radiology. One illustrates how different scanners have improved, also how the communication system for image archiving can help doctors and finally the outlook on the future of radiology. For starters, how has technology changed the field of radiology? Since the discovery of X-rays, the need and desire to study the human body and diseases without any intervention has emerged. Over the past fifty years, a revolution has occurred in the field of radiology that has profoundly influenced medicine. “The ability to produce computers powerful enough to reconstruct accurate body images, yet small enough to fit comfortably in the radiology department, has been the major key to this progress” (Gerson 66). The core of the extensive development of radiology consists of four diagnostic techniques: computed tomography (CT), digital subtraction angiography (DSA), ultrasound and magnetic resonance imaging (MRI). These diagnostic imaging methods provide accurate information never seen before. In the context of this informational advance, radiologists have expanded their role as diagnosticians. Gerson writes, “With the advent of computer-enhanced imaging and new interventional techniques, these physicians are able to take an active part in performing therapeutic procedures” (66). A breakthrough in radiology in 1972 was computed tomography discovered by Godfrey Hounsfield and Allan Cormack. Unlike standard radiography, computed tomography rotates the 2002): 75- 80.
