Digital X-ray is Vision and Reality

 At RSNA 2007, vendors are offering the best features from DR and CR to help users get the most bang for their buck, whether those users are large medical centers or small physician practices. Vendors know that space, time and budgets are all being squeezed—so look for more compact, affordable equipment that offers flexible positioning, speedier throughput and further improvements in image quality. User-friendly software, touchscreens and preview technology are just some of the features designed to let technologists get their job done while staying with the patient as much as possible.
