Images of the human body are derived from the interaction of energy with human tissue. The energy can be in the form of radiation, magnetic or electric fields, or acoustic energy. The energy usually interacts at the molecular or atomic levels [1]. On Friday evening, 8 November 1895 Röntgen, Wilhelm Conrad (also sometimes spelled Roentgen) discovered a “new kind of ray” that penetrated matter. Röntgen professor of physics at Julius Maximilian University of Wurzburg, named the new kind of ray X-strahlen “X-rays” (“X” for unknown). [2] X-rays are electromagnetic waves having energy in the general range of approximately one to several hundred kilo electron volts (keV). In medical X-ray imaging, the X-ray energy typically lies between 5 and 150 keV, with the energy adjusted to the anatomic thickness and the type of study being performed [3]. X-ray technology are divided into two main groups digital and conventional film-screen system, digital radiography is a form of X-ray imaging, where digital X-ray sensors are used instead of traditional photographic film. X-rays are known to cause malignancies, skin damage and other side effects and they are thus potentially dangerous. Therefore, it is essential and in fact mandatory to reduce the radiation dose in diagnostic radiology as far as possible. T
