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.

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.
Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
