The significant increase in radiation exposure and uncertainty regarding the risk of cancer have raised concerns leading to a recent change of direction within medical imaging. Several initiatives to lower dose levels are being established and many healthcare providers have initiated dose reduction programs to guard patient safety and to comply with new regulations. 

The radical increase in patient exposure to radiation from medical imaging over the last two decades has created great concerns about its inherent risks. Today, one of the highest priorities on many hospital agendas is to break this trend by achieving improved control of the radiation exposure to their patients.
