Since 1993, the number of CT examination has been dramatically increasing by approximately 10% per year [
1]. For all ages, up to 62 million CT examinations were performed in the United States during 2006 and the radiation dose from CT accounts for nearly half of the total ionizing radiation dose from medical imaging. Among the total CT examinations performed from 2004 to 2006, approximately 10% of the procedures were in children [
1]. Children have a higher risk of cancer from radiation than adults for several well-recognized reasons [
2], especially longer life expectancy. Additionally, radiation to organs such as breast, eye lens and thyroid are of concern during CT. For these reasons, strategies to optimize radiation dose to these radiosensitive organs are critical in this population. …
