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
5. Advantage: Possibilities of digital postprocessing
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.
