Abstract

Over the past 5 years, over 50,000 CT scans have been performed to help track patient illness. The radiation associated with this procedure may be a risk factor for certain diseases, such as cancer, so it is necessary to ensure that patients are receiving doses that are as low as possible. Starting in mid-2009, most scanners at the NIH began providing dose information. Our goal was to fully extract this information, and examine the dose changes after dose reduction initiatives.
