5 Benefits of Digital Radioscopy (DR)

Digital Radioscopy (DR), which is a discipline of non-destructive testing (NDT), uses X-rays to search for imperfections in components. Sometimes it is also referred to as digital radiography, although this is more of a medical technology term, as radiography initially only describes conventional X-rays. In digital radioscopy, rays are generated with a source, which penetrate the component to be inspected and are processed on the other side by a detector to form a live image on a monitor.

The 5 benefits of digital radioscopy (DR)

The biggest advantages of digital radioscopy/radiography (DR) are

  • Cost-efficient acquisition
  • Reduction of radiation exposure
  • No waste of space through storage
  • Environmental protection
  • Possibilities of digital postprocessing

1. Advantage: Cost-efficient acquisition

Despite the higher acquisition costs of a digital X-ray system, the total cost of ownership decreases. The film for analog X-ray images no longer needs to be purchased and developed at high cost. Likewise, the time for a long development is saved. With a digital X-ray system an image is created and displayed in only 3 seconds. The variable costs are thus greatly reduced.

2. Advantage: Reduction of radiation exposure​

In analogue radioscopy, radiation exposure is not considered harmful if not used too frequently. However, digital radioscopy has up to 80% less radiation exposure than the analogue version and is therefore much gentler on the object being radiated through.

3. Advantage: No waste of space through storage

The digital images are stored on a hard disk and thus hardly take up any space during storage, as they would have taken up film rolls with the conventional method. This means that they have almost unlimited storage space, making them easy to archive. Since the data can be transported digitally quickly, image evaluation no longer needs to be carried out on site, but can also be carried out externally. It is also possible to archive images compactly and at low cost permanently on a CD.


4. Advantage: Environmental Protection

The images are no longer produced in a darkroom or with a developing device, but digitally. This means that consumables such as chemicals or film tapes are no longer needed and used up. There is a saving in cleaning up and the repeated disposal of hazardous waste. The environment is less polluted and thus protected.

5. Advantage: Possibilities of digital postprocessing

With the help of special tools, the digital images can be post-processed on the computer on site or at any other location, in order to make imperfections easier to distinguish and recognize. Thus immediate results are visible. Likewise, no repeat shots have to be taken, as there is no over- or underexposure.

Bonus: How can digital radioscopy be improved?

Digital radioscopy (DR) and working with imaging plates is becoming increasingly popular, but other imaging techniques such as Phased Array (UT) also offer image material that can be digitally evaluated. To save time and nerves during examination and evaluation, the right tool should be used. Often an interpretation of anomalies is also not clear, so one asks a colleague for advice. The sentin EXPLORER facilitates the evaluation by automatically analyzing and marking of imperfections.
