New radiation protection technique results in reduced physician exposure


A new radiation protection technique can significantly reduce physician radiation exposure during coronary angiography, according to a researcher at the University of Maryland Medical Center in Baltimore, MD.

Using the new device, physicians monitor patients’ angiograms and control exam table movement from behind a lead plastic shield. A newly developed extension bar allows the physician to remain safely behind the shield and still retain table control for panning, according to Martin Magram, MD, developer of the new technique and assistant professor in the department of diagnostic radiology.

Dr. Magram recorded radiation exposure to various parts of the physician’s body in a new study using the technique during coronary angiography on 25 patients. He compared the physician’s radiation exposure during the same procedure on 25 patients using conventional radiation protection. Using the new equipment, Dr. Magram found 90% reduction in radiation exposure to the physician’s head, arms, and legs.

"Current technique requires that physicians wear heavy lead gowns during radiation procedures. This new technique may free physicians from the need to wear lead gowns," said Dr. Magram. "As the sophistication of radiological diagnostics has increased, it is tragic when a physician can no longer perform procedures because the lead gowns cause onset of neck or back degeneration and the physician becomes unable to tolerate the weight of a lead gown."

This new technique may preserve these physicians’ ability to benefit patients. "It may extend by years their ability to apply the skills they have developed over long careers of serving patients," said Dr. Magram.

"America’s medical community adheres to the ALARA principle (as low as reasonably achievable) in the use of radiation for diagnostic tests in patients," Dr. Magram said. "We must be equally vigilant in protecting the members of the health care team from radiation exposure as they administer diagnostic and therapeutic procedures," he said.

"The development of many new radiation techniques improves our ability to deliver medical care. New methods of radiation protection must parallel the development of new radiation techniques," Dr. Magram said.

"The key is to limit medical workers’ radiation exposure with effective and easy-to-use techniques," he said, "and the use of this extension bar and lead plastic shield may be such a technique."

Dr. Magram will present the full results of the study on Wednesday, May 3, 2006 at the American Roentgen Ray Society Annual Meeting in Vancouver, Canada.

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...
