RSNA 2011: New personal dosimeter permits real-time monitoring of radiation exposure
The increasing emphasis on lowering radiation doses during diagnostic and interventional imaging has relevance to safety for both the patient and physician. A new dosimeter device that is worn by the physician has relevance to both. The device quantifies radiation exposure for real-time display on a video monitor. A single-institution study testing the device primarily in interventional procedures demonstrated large reductions in radiation exposure not only to the interventionist but to all of the members of the procedure team, including the anaesthesiologist. The reduction in radiation exposure is attributed to changes in behaviour by the interventionist when made fully aware of exposure levels. The author of this study, interviewed at the RSNA, believes this technology is important and predicted that this or similar devices will soon be a standard. The device he evaluated is commercially available and has been incorporated into his own practice.
