Digital Radiography: Definition, Working, Advantages and Difference

During the past one-two decays, Digital Radiography (DR) overtaking conventional radiography in many industries as well as medical sectors also due to convenience to use and higher quality in general.

The future of radiography will be only and only digital in any industries where radiography is needed and then Digital radiography will play a crucial role in the upcoming future.
Digital Radiography is booming in the industrial sectors as well as medical sectors. various companies are preferring digital radiography instead of conventional radiography.
So, here I will discuss all digital radiography, with complete information, from start to end. So, Scroll with me and dwell deep inside the digital radiography.

What is Digital radiography?

Digital radiography (DR) is an advanced form of x-ray inspection, which produces a digital radiographic image instantly on the computer.


Radiation is observed or scattered when it passes through the object, if there is any variation in thickness or density in the object, affects the film exposure. Usually, it shows in dark areas if there is any type of variation is observed.

Advantages of Digital Radiography- 

There are several benefits of digital radiography, some of which are given below-
1. Enhanced image quality: Digital radiography produces better image quality than conventional radiography. Because more focused radiation is bombarded on the object and digital radiography removes manual mistakes also, that also enhance the image quality at the optimum level.

2. Reduced radiation Dose: The main advantage of this type of radiography is that it greatly reduces radiation exposure because it effectively reduces 75% of the total radiation and ensures radiation safety. 

3. Less Resources-  As you know, Digital radiography uses the automated process, and hence that greatly reduces various resources that are used in conventional radiography.
4. Easy to use- Digital radiography is very convenient in terms of uses. It is free from conventional processes like film processing and various measuring actions required in conventional radiography.
5. Less Processing Time: Digital radiography uses electronics processing and that cuts the various processes like processing film, developing, drying film, and other various work that takes too much time in conventional radiography. 
6. Easy Sharing- Time to say goodbye to the Conventional Radiography, Where storing and organizing them was the biggest hurdle. Now Digital Radiography plays a crucial role in terms of storing data of the outcome result. So, You don’t need to keep carrying along bulky envelopes filled with x-ray films.
This technique uses a digital medium to store those files, Which provides easy Access as well as protection regarding unauthorized access.  
7. Enhanced Quality- Hence, Digital radiography reduces the various manual process like processing films and other manual terms which cause several errors, This leads to the enhanced overall quality of radiography and productivity too. 

Applications of digital radiography-

Digital radiography uses in various industries and sectors, Here are some applications of DR in various sectors-

  • Detection and classification of pneumoconiosis
  • Clinical application
  • Implantology
  • Density measurement
  • Medical Application
  • Industrial application

Difference between Digital Radiography and Conventional Radiography-

Here I will compare  Digital radiography and Conventional Radiography side by side.

Conventional Radiography-

  • Fixed Contrast- The contrast of the radiograph is fixed in this type of radiography, You can not change film density If needed.
  • Limited View- It gives only a 2D view of a 3D object, you can not zoom in or zoom out or Flip the image If needed.
  • Duplicacy– Conventional Radiography is the best technique to create a duplicate image, If you want to show the clean image without any cavity to the client, You just need to take a shot from the Passed area, and bolllaa, You are good to go.
  • Mobile-friendly– Set up of convention type of Radiography can be mobilized, if an object can not move.

Here is the detailed guide of Conventional Radiography, to give more information about the same.

Digital Radiography-

  • Variable Contrast- The contrast of the radiograph can vary, You can adjust the contrast of the radiograph according to your need.
  • Unlimited View-  It gives a very detailed and crisp image of the object and you can also zoom in and zoom or flip according to your needs.
  • Time-Saver- Digital radiography saves an enormous amount of time Because it combines all needed equipment in a single place and can operate at ease with approx single manpower.

These are the basic side-by-side comparison of both types of Radiography, Both are suitable at their place Because of mobility in some cases.

For Detailed comparison knowledge regarding the same, You can give watch this video clip given Below…




Digital radiography is the new emerging technique in the NDT method, more in the medical and clinical sectors. The quick and instant result is the main highlight of Digital radiography.
In this article, you got all about Digital radiography, from scratch to end.
Hoping, This article gives you some value and stretches your bowl of knowledge a little bit,
If so, then share to need one and help to stretch those one knowledge too.
