Abstract
The U.S. Food and Drug Administration (FDA) has been concerned with minimizing the unnecessary radiation exposure of people for half a century. Manufacturers of medical X-ray imaging devices are important partners in this effort. Medical X-ray imaging devices are regulated by FDA under both its electronic product regulations andits medical device regulations. FDA also publishes guidance documents that represent FDA’s current thinking on a topic and provide a suggested or recommended approach to meet the requirements of a regulation or statute. FDA encourages manufacturers to develop medical devices that conform to voluntary consensus standards. Use of these standards is a central element of FDA’s system to ensure that all medical devices marketed in the U.S. meet safety and effectiveness requirements. FDA staff participate actively in the development and maintenance of these standards, often advancing or introducing new safety and dose management requirements. Use of voluntary consensus standards reduces the amount of time necessary to evaluate a premarket submission and reduces the burden on manufacturers. FDA interacts with industry and other stakeholders through meetings with industry groups, public meetings, public communications, and through the development of voluntary consensus standards. In these interactions, FDA staff introduce new concepts for improving the safety of these devices and provide support for similar initiatives from professional organizations. FDA works with all stakeholders to achieve its mission of protecting and promoting the public health.
