What is Radiographic Digital Imaging?
Radiographic digital imaging is a specific type of radiography which relies on a digital media to capture and present the pictures it takes, rather than the more classic use of photographic film. Radiographic digital imaging has become a popular form of displaying radiographic images, particularly medical x-rays. Most radiographic digital imaging is done using x-rays, though some techniques may utilize gamma radiation as an alternate method for providing images. X-rays are short wavelength radiation, with photons created by an electron process. This is in contrast to gamma radiation, which often shares the wavelength of x-rays, but has as its source a subatomic activity such as the interaction of electrons with positrons. Occasionally, radiographic digital imaging may use neutrons in order to form a picture. This is primarily used for industrial imaging purposes, though it is sometimes necessary for security as well. Neutron imaging is used when traditional x-ray and gamma-ray radiatio
Digital radiology may represent the greatest technological advance in medical imaging over the last decade. The use of photographic films for X ray imaging will be obsolete in a few years. An appropriate analogy that is easy to understand is the replacement of typical film cameras with digital cameras. Images can be taken, immediately examined, deleted, corrected, and subsequently sent to a network of computers. The benefits from digital radiology are enormous. It can make the facility filmless. The referring physician can view the requested image on a desktop personal computer, often with the report, just minutes after the examination was performed. The images are no longer held in a single location; they can be seen simultaneously by physicians who are kilometres apart. In addition, the patient can have all his or her X rays on a compact disk to take to another physician or hospital.
