Filmless System Puts X-Ray Images On The Web
... Instead of printing an image to film, computed radiography
reads X-ray platesand composes a matrix image. The computer transmits digital image informationand creates a high-resolution image. At the click of a mouse, the images appear and can be manipulated on acomputerscreen. Images are stored on op...
Studies: New imaging technique improves X-rays of breast tissue

in that an "analyzing" crystal is placed in the X-ray beam between the object being studied and an image-creating medium such as film, X-ray plate or digital detector, Sayers said. The silicon crystal diffracts a particular wavelength of X-ray throug...

Research reveals no benefit of rapid MRI over X-rays in patients with low back pain
...at X-rays are not useful. By looking at the images radiography
