what is Digital Radiography System

Digital radiography (DR) is an advanced type of x-ray examination, which produces an electronic radiographic picture promptly on a computer. This technique makes use of a level panel detector to capture data during object examination, which is immediately transferred to a computer without the use of an intermediate cassette.

Digital Radiography Technology

There are two types of digital imaging systems used in intraoral radiography  –

  1. Computed Radiography(CR)
  2. Digital Radiography(DR).

CR uses a Photostimulable Phosphor (PSP) cassette to capture the image.

DR uses Amorphous Silicon (a-Si) or Cesium Iodide (CsI) Flat Panel Detector.

Flat Panel Detectors (FPDs) are the most common kind of direct digital detectors. 
They are classified in two main categories:

Indirect

The most common material used in commercial FDP is FDP Amorphous silicon (a-Si). To convert the X-rays into light scintillator are combined with a-Si detectors in the outer layer of detector’s and gadolinium oxysulfide (Gd2O2S) or caesium iodide (CsI) are used in making its outer layer. The a-Si detector is called an indirect imaging device because of this conversion. The a-Si Photodiode layer is used as a channel where light passes through and is converted into a digital output signal. Fiber-coupled CCD  or (TFT) thin-film transistors are then used to read out the digital signals.

Direct

X-ray photons are transformed directly into charge by using FDP (a-Se) Amorphous Selenium that is why it is also called direct detectors. High voltage bias electrodes are used in the out layer of its flat panel. Electron-hole pairs are created by X-ray photons in a-Se, and the potential of bias voltage charge is responsible for the transit of these electrons. TFT array, microplasma line addressing, active matrix array, or electrometer probes are then used to read out the charge pattern when all the holed are replaced by electrons.

What are the Advantages of Digital Radiography?

Digital radiography offer many advantages to the non-destructive testing community, including:

What is the Difference Between Digital Radiography (DR) and Computed Radiography (CR)?

Comparison Image of CR12bits & DR 14 bits

DR 14 bits & CR 12bits Comparison

Linear detector arrays and active matrix flat panels are used in digital radiography systems, dynamic matrix array of (TFT) thin-film transistors and photodiodes are deposited under their detection layer. Digital data become available for analysis in no time through digital radiography.

Photo-stimulated luminescence screens are used by computed radiography cassette for X-ray images instead of X-ray films. Stored data gets converted into the digital image when computed radiography images go into radar. The rigid holder is not required by computed radiography images because they are flexible. A detector can fit in curved areas with flexible cassettes.

 

Both (DR) digital radiography and (CR) computed radiography has a wide range of functions and can eliminate noise but digital radiography has advantages over computed radiography. Digital radiography is more efficient than computed radiography and produces better quality images than computed radiography. Digital radiography is faster, more advanced, and less in price than computed radiography, these all features make digital radiography a better choice and more advanced machine.

  • Computed Radiography (CR) X-ray

  • Comparison

  • Investment & CostsLower initial investment, more requirement for maintenance. 3 year ownership cost of CR is very expensive considering the following:

    - IP Plates recurring cost
    - Service Cost of the CR reader
    - Work flow inefficiencies
    - Higher dose required

  • InstallationsCan be retrofitted to existing installations
  • Dose (DQE)DQE is better than Film but lower than DR. With time the IP plate tends to deteriorate, by which the dosehas to be increased to geta diagnosable quality image.
  • Labor-intensiveLabor-intensive due to need for cassette transfer to plate reader
  • Image QualityImage can be digitized but at much lower resolution. Similar to quality of DR at high-dose levels and can degrade in the time it takes to process the cassette.

  • SpeedOnce the image is captured, it has to be scanned, in CR reader, so the average time is more than 3 minutes. Additional steps to obtain the image.
  • StorageDigitized image storage is more space efficient than film
  • DurabilityImage Plate deteriorates with time thus quality of the image also decreases with usage


    - Every 6 to 8 months new IP plates have to be purchased (depends on usage)

  • Work LoadManual Driven with IP plates need to be physically carried and scanned to get the image.
  • Digital Radiography (DR) X-ray

  • Investment & CostsHigher Initial Investmen, less requirement for maintenance. 3 Years ownership cost of DR achieves optimum return on investment in addition to:

    - Better image at lower dose.
    - Less RT Labor.
    - Higher productivity

  • InstallationsAll new setup necessary
  • Dose (DQE)Flat panel detectors allow low dose. DR outperforms CR both in DQE. Some research shows that Dose can be reduced as much as 50%
  • Labor-intensiveCompletely digitized setup
  • Image QualityHigh-quality digital image. Better image quality with respect to contrast and detail detectability.

  • SpeedImage is immediately displayed within 10 seconds. Faster throughput and save more resources.
  • StorageEasy storage and instant access to archive images
  • DurabilityOver 1 million exposures
  • Work LoadThe workflow of DR achieves complete automation. Higher patient turnaround time.
