Now in digital...
We use the lowest radiation, handheld device that we know of to take digital radiographs. The equivalent dosage is equal to spending 8 minutes in the sun.
Digital radiology may represent the greatest technological advancement in medical imaging in the last decade. The use of radiographic films in X ray imaging might become 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 immediately acquired, deleted, modified, and subsequently sent to a network of computers.
The benefits from digital radiology are enormous. It can make a radiological facility or department filmless, eliminating chemical processing of films. The referring physician can view the requested image on a desktop or a personal computer and often report in just a few minutes after the examination was performed. The images are no longer held in a single location; but can be seen simultaneously by physicians who are kilometers apart. In addition, the patient can have the x ray images on a compact disk to take to another physician or hospital.
