An independent study presented at the 41st Annual Conference on Radiation Control, held 18–21 May 2009, concluded that the NOMAD handheld dental X-ray system produces staff radiation-exposure doses so low that the vast majority of users received no measurable radiation dose.
This conclusion contradicts the common misperception that operator exposure would be higher with a handheld X-ray system.
The study also found that the image resolution and contrast of the NOMAD were superior to the wall-mounted system tested, and the leakage and scattered radiation were lower.
In addition, the study reported that additional operator protection measures, such as the use of lead aprons or stands, are not warranted. According to the study, this is largely due to improved shielding techniques incorporated into the NOMAD,
The paper, “Image Quality and Radiation Dose Comparison for Intraoral Radiography: Hand-held, Battery Powered versus Conventional X-ray Systems,” was delivered as part of the annual meeting of the Conference of Radiation Control Program Directors (CRCPD) in Columbus Ohio in May 2009. Edgar Bailey, MSEHE; Joel Gray, PhD; and John Ludlow, DDS, authored the study.
The NOMAD handheld X-ray system is manufactured in the USA by Aribex of Orem, Utah, and was invented by the company’s CEO, Dr D. Clark Turner.
“This study verifies what we have known for some time, that our handheld X-ray device is at the cutting edge of X-ray technology in terms of quality and safety,” said Dr Turner. “Add to that the convenience of the lightweight handheld design and we have a product that has changed the way X-rays are taken in a dental office and has opened the way to take X-ray imaging to those who cannot come to a dental office.”
The NOMAD is cordless and rechargeable and requires no installation so it can easily be taken from operatory to operatory in a dental office. The operator can stand right next to the patient while taking the X-ray without having to leave the room.
In addition, because it does not require direct connection to an AC outlet, it has been widely used for humanitarian work in some of the most remote areas of the world.
A copy of this independent study as well as more information about the NOMAD is available from Aribex, a privately owned, Orem, Utah-based company founded in 2003 with the mission to develop, manufacture and market new technologies in the X-ray radiography fields. Aribex flagship products are the NOMAD and the NOMAD Pro handheld X-ray systems.
