The bandwith of products for digital radiography offers a huge variety. Existing X-Ray systems with their spatial conditions, appliable recording techniques and their individual throughput of patients can be equipped with specific systems.

 

We want to show you some ways how to digitize your house. We want to make you curious and answer your questions.

Solutions

Hereinafter we want to show you some different ways of digital solutions - for existing X-Ray systems as well as for complete new systems

 

classical Bucky/Wall-Tripod Systems

  • universal, frequently in use
  • upgradable with CR and DR systems, e.g. in following combinations:
    • for a very high throughput with multiple X-Ray systems:
      • ImagePlate systems (CR) with multiple cassette inserts
      • WIFI detector systems (DR)
    • for high to average throughputs:
      • high quality ImagePlate systems (CR) with single inserts
      • WIFI detector systems (DR)
    • for small throughputs
      • smaller CR systems
      • wired detector systems

 

Swivel Bar

  • limited spectra of recording techniques - depending on equipment
  • upgradable with following combinations:
    • wired detector (without the possibility of held shots - thus, these images can be received using different recording techniques)
    • wired detector systems (held shots are possible)
    • CR / Image plate solutions

Column base system 

... X-Ray different than you may be used to. Equipped with a wired flat panel detector, all known recording techniques (depending on equipment) can be realized. 

Detector and Image Plate systems

Both technologies have their raison d'être. As well image plate systems as detectors can produce high follow-up costs - or avoid them.

Computed Radiography (CR, Image Plate)

The technology of image plates (computed radiography) offers the advantage, that the existing X-Ray system can be kept most times. Instead of film strips, image plates are exposed to radiation. Electrons, positioned in the molecules of the image plate, are raised to a higher energy level by the used radiation. When putting the plate into a digitizer, the system can convert the information and form an image. At the end of the reading process, the informations stored on the image plate are erased.

Advantages: easy upgrading of existing X-Ray systems,small cassette sizes for held shots, stitching functionality with one shot, cassettes are easy to handle, lower risk of dropping plates

 

Direct Radiography (DR, Detectors)

In comparison to CR systems, DR systems neither need any digitizing station nor cassettes or image plates. Two kinds of detectors are existing: electro-direct detectors and opto-direct detectors. The surface of flat panel detectors consists of smallest image elements (pixels). When talking about electro-direct systems, the radiation is transferred directly (via amorphous selenium) into electric charge. When talking about opto-direct flat-panel-systems, the radiation energy is first transferred into light (via amorphous silicon) and afterwards converted into electric charge.

Advantages:  immediate availability of images, no electromagnetic digitizers

Resolution instead of guessing

 

Image Acquisition / first editing

The variety of algorithms usable for image acquisition are huge. Enhancements, interpolations and anti aliasing are just a few of them. In best cases, image acquisition software is being delivered by the CR/DR manufactoror. But we have to keep in mind, that even the best image acquisition software does not replace the need of quality and resolution of the CR/DR system.

Pixel vs. millimeters

10 pixel per mm means, a resolution of 100µm is realizable. In the same way, a resolution of 87µm equals 11,4 pixel per mm. Concluding, a resolution of 87,5 µm is 14% better than 10 pixel per mm.

Attention: Image plate systems, which provide high resolutions but are set up with a lower resolution (to save reading time) provide image quality which can be 30% less than usual - without the medical facility knowing about it.

Constancy Checks which are later performed with high resolution again, could lead to wrong impressions.So please take care that your image plate systems meets your requirements for speed and quality.
