Performances

The best technology inside your system

All Trixell detectors offer excellent X-ray absorption and processing capabilities ensuring high quality images at a low exposure. Combining technology developed by Trixell, the joint venture between Thales, Siemens and Philips for the advancement of the Pixium® flat-panel detectors (aSi), Trixell also proposes CMOS technology (Complementary Metal Oxide Semiconductor). These imaging systems can be used in a variety of digital X-ray imaging applications and have several useful characteristics:

  • Low operating power;
  • High-speed readout;
  • Capable of on-chip integration of electronic circuitry;
  • Production of digital signals without external converters.

Top-of-the-range Scintillator

Benefiting from 60 years of experience, we manufacture the Cesium Iodide (Csl) scintillator using its unique in-house manufacturing process. The Indirect Deposition process brings higher efficiency in the transmission of light to the photodiode matrix resulting in a better image quality with a lower dose.

Low noise Electronics

We have achieved the lowest image noise available in the market thanks to 20 years of experience developing state-of-the-art electronic components.

Optimised pixel size

Optimised pixel size versus dose and diagnosis capability for a given technology.

  • All these factors ensure an optimized Detection Quantum Efficiency (DQE)

    An high DQE, is a key indicator reflecting the overall image performance in relation to the radiation dose. The most important information for diagnosis in radiography is obtained in these spatial frequencies from 1 to 2 lp/mm as you can see below. Pixium detectors have largely demonstrated their ability to generate high-quality images, while reducing exposure by 30 to 50% versus the current average. As an example of these cutting-edge technologies, the Pixium 3040 is offering a DQE at a low dose : 35 % at 2 lp/mm, RQA 5, 20 nGy.

  • Modulation Transfer Function (MTF)

    Optimum image quality for a Flat Panel Detector comes from a high DQE accompanied with a high MTF. DQE reflects the capacity to detect information at low dose, and MTF is how this information is structured. Between DQE and MTF, the most important parameter for your Flat Panel Detector choice must be the DQE as a low DQE cannot be compensated by post processing. Pixium detectors have demonstrated their ability to generate high-quality images, while reducing exposure by 30 to 50% versus the current average as you can see on this radiological image.

  • Reliable and durable technology that fulfils daily work

    • An extensive testing process: in order to ensure efficient day-to-day procedures in the most intractable situations, our products undergo a wide range of robustness tests that ensure all results above the FPD market. From a 1 meter drop, to the repeated insertion of the battery (15 000 times), through material abrasion (more than 55 000 rubs of material), impacts tests (iron ball all 500g. at a height of 130 cm), or pressure of more than 300 kg, etc. All our detectors are fully tested and qualified and are sent to you only when we can ensure their longevity. Our in-house CSI technology also helps keep Pixium detectors’ performances over the time.
       
    • A low return rate: 95% in 15 years thanks to years of experience in design improvement and manufacturing process control. Most of Trixell detectors released in 2001 are still in operation.
