Dual energy solutions for the food industry

The powerful dual energy capability of our photon counting detectors coupled with market leading sensitivity and image resolution, brings new levels to material differentiation in X-ray imaging. This capability helps our food production customers with the identification of foreign objects during processing. With the performance of our XCounter detector in partnership with the configuration of our software, materials can be seen, measured, and identified through software mechanisms such as subtraction imaging. Reliable and repeatable data enables solutions to be hardwired into the process line.

The dual energy capability of XCounter group detectors is used in a wide range of food applications such as fish bone filleting. Our photon counting detectors exceed many other detectors in the market in their ability to discern difficult materials such as olive stones in olives. Our high-speed products with speeds of up to 10,000lps, and our adaptable geometry configurations giving detector lengths of up to 0.5m make XCounter detectors ideal for conveyor belt based inspection. To conform to the high quality standards demanded by the food industry, our detectors are manufactured in our ISO13485 accredited facilities, ensuring all of our detector solutions meet the most stringent of quality assessment during production. Our detectors deliver consistent unparalleled performance.

New Levels of material differentiation

The direct conversion CdTe CMOS technology at the heart of our detectors mean that you will not suffer from the ghosting, lag issues or blurring at high energies to which some ordinary TFT based flat panel detectors are sometimes prone. All of our detector range have market leading performance achieving Detector Quantum Efficiency (DQE) of 85% @ RQA5 spectra and a Modulation Transfer Function (MTF) of >80% @ 2lp/mm. And our Hydra product range, with its ultrafast frame rates of up to 20,000fps set a new standard in X-ray imaging, bringing high performance X-ray imaging to production lines that are constantly looking to increase volume throughput.

Beyond our market leading detector capability, our proprietary Charge Sharing Correction (CSC) software enhances the resolution and sensitivity performance of our detectors to levels that cannot be achieved in any other technology. And our Real-time Temperature Correction (RTC) software creates stable and reliable detectors with longevity.

The dual-energy configuration of our detectors mean that they can be calibrated to “look” for specific materials in your production line such as pips. This tuning enables automated inspection processes to be established. Explore our GALLERY for examples of our image performance.

Technology

XCounter has a solid foundation in both integrating and photon counting state of the art X-ray detector technology.

The basic component in our detectors is a conversion material, which converts the X-rays into electrical signals, and a CMOS (ASIC) which transforms the electric signals into a datastream of either the integrated electric charge or the number of photons which has entered each pixel. This data is then used to create a digital image which is either two- or threedimensional, depending on the scan geometry.

Our solid state detector uses CdTe which is a direct conversion material. When an X-ray photon enters the material it is converted directly into an electric signal which is captured, measured and finally processed into an image. This provides significantly better Modulation Transfer Function (MTF) and Detection Quantum Efficiency (DQE) compared to scintillation detectors due to the high sensitivity and very good stopping power for high energy photons. By combining the CdTe conversion layer with our custom ASICs (CMOS) we can supply detectors that support integrating as well as photon counting modes, fast readout and low power consumption.
