Standardized Methods for Measuring Diagnostic X-Ray Exposures-7A7EF93C

The task group on “Standardized Methods for Measuring Diagnostic X-ray Exposures” was formed by the Diagnostic X-ray Imaging Committee to provide a standardized method for radiologic physicists to use in complying with Section DR.2.2.10.2 of the JCAHO Standards. Section DR.2.2.10.2 reads as follows: DR.2.2.10 Provisions that a qualified physician, qualified medical radiation physicist or other qualified individual DR.2.2.10.2 monitor doses from diagnostic radiology procedures. It should be noted that, for compliance with this standard, radiographic exposure measurements must be room specific and should he determined for commonly used projections in each room’. The topics covered in this document include procedures for measuring patient exposure, suggested phantoms for use with automatic exposure control (AEC) systems, recommended common projections for which exposure data should be measured, references to national average exposure data for these common projections, and a reference bibliography. Measured patient exposures should he compared to national average values. Corrective action should he taken if high patient exposures or room-to-room discrepancies are noted.
