Digital radiography is a type of x-ray imaging. However, here instead of the traditional photographic film, digital x-ray sensors are used. It is a time efficient process and saves a lot of time through bypassing the chemical processing and also has the capacity of digitally transferring and enhancing the images. At the same time, here less radiation is used for producing an image of the same contrast to the conventional radiography.

The digital radiography is operated by a system that contains these functional components like a digital image processing unit, image and data storage devices, a digital image receptor, an image management system, interface to a patient information system, a display device having viewer operated controls and a network of communications.

Advantages of digital radiography

* It provides you high resolution that is required for examining the complex conditions as well as making complex diagnosis confidently and rapidly.

* The new design of the sensor provides high comfort to the patients by removing the dead zone factor and allowing for the vertical placement.

* Due to the advances in the field of technology all the sensors come with increased sensitivity that permits the physician to reduce the dose of radiation upto 10-40 % depending upon the size of the sensors.

* The image of the patient can be archived, processed and retrieved. Multiple images will be displayed on the screen at the same time and also you can share the images with your colleagues, team members or insurance companies.

* It also helps the dentists in finding about 20% more cavities in your dental area as compared to the traditional methods.

Digital radiography use technologies like electronic sensors. Here the x-rays are converted into light that are then captured by a CMOS or a CCD image sensor. Some of them may also use hybrid arrangements means, first the x-ray is concerted to electricity that is then captured by the reading section of the CMOS technology as an image. Digital radiography is nowadays used in orthopedic practices, imaging centers, private clinics, and outpatient areas of large hospitals and also in other small or medium hospitals.
