Digital X-rays, or digital radiography, are x-ray images, where instead of the traditional photographic films, digital x-ray sensors are applied. Digital x-rays save time and are more convenient than traditional x-rays. They do not need to go through the chemical processing. Also, they can be expediently transferred from one location to another and the images can be enhanced very easily.
This x-ray image is completely filmless, which means that it does not involve traditional photography films. It consists of a digital image capture device, which efficiently captures the x-ray image and makes it presentable. Such image can easily be used for the medical records of the patient without any hassle or inconvenience and without wasting any time.
The digital x-ray image is available for preview and record purposes instantaneously. The dynamic range of the digital image is extremely wide which makes the viewing and observation easier. Moreover, special image processing techniques can be easily applied to the digital image. This makes it more presentable and understandable. One advantage which digital x-rays offer to healthcare centres and hospitals is low cost. As they eliminate the expense of film processing, managing and storing.
The digital image capture devices necessary to obtain the digital x-ray image are available in two variations. These two variations are the Flat Panel Detectors (FPDs) and the High Density Line Scan Solid State Detectors. The Flat Panel Detectors are further classified into two variations; Indirect FPDs and Direct FPDs.
