Real-Time Measurement and Audit of Radiation Dose to Patients Undergoing Computed Radiography

Abstract
A real-time patient dose monitoring system for auditing computed radiography is described. Technical data from each exposure, and for every examination type are collected and sent by a network to a workstation, which calculates the moving average values of entrance skin dose and dose-area product from the 10 most recently examined patients. Comparison of averages with reference values generates warning messages if reference values are exceeded, prompting corrective action if necessary. (C) RSNA, 2002.
