Abstract
In an effort to reduce radiation exposure from computed tomography (CT), practitioners and facilities need to monitor radiation exposure while delivering high-quality diagnostic examinations. One way to minimize a patient's exposure to radiation from CT is the use of an automatic exposure control device. Current research is focusing on these devices and their actual benefits to patients. To assess the effectiveness of such a device, analysis of radiation doses per CT examination must occur. Machine-specific dose-length product and/or CT dose index are the only indicators of specific dose levels. This project compares current levels of radiation exposure to patients undergoing CT scans of the head versus the national levels as evaluated by the Nationwide Evaluation of X-ray Trends program.
