Digital X-rays are like the digital cameras we have today. They still use X-rays as the standard X-rays; the only difference is that their sensors are connected to a computer and not a film. This enables the modern X-ray to capture clearer and more accurate images as compared to its predecessor.
X-ray imaging (radiography) is still the most commonly used technique in radiology. To create a radiograph, a part of the body is exposed to a very small quantity of X-rays. The X-rays pass through the tissues, striking a film or detector to create an image. X-rays are safe when properly used by radiologists and technologists specially trained to minimize exposure. No radiation remains after the radiograph is obtained.
