A multi-chip x-ray imaging detector with the ability to provide spectral material-sensitive “color radiography “. It suits industrial devices such as CT scanners and supports hardware-based Time-Delayed Integration. The camera is equipped with Medipix3 photon-counting chips.
Industrial spectral scanner camera with a large area imaging detector
The large area imaging detector WidePIX CHROMATIC (former name WidePIX MPX3 L) is composed of Medipix3 hybrid detector electronics tiles. Each tile (256 x 256 pixels) is attached to a silicon or cadmium telluride sensor. Therefore, the whole detection area of the WidePIX CHROMATIC is fully sensitive, and there are almost no gaps (less than 4 pixels) between sensor tiles.
Each pixel has two integrated 12-bit digital counters and two energy discrimination thresholds. The counters store number of registered particles, with the possibility to set desired energy threshold. Both counters can be joined to a single 24-bit counter, providing enhanced dynamic range.
The particle counting principle eliminates any additional noise generated by the sensor or electronic readout. It allows for acquiring X-ray images with very high contrast and wide dynamic range. Therefore, even low-contrast structures such as plastic or soft tissue are easily detectable in X-ray images.
The energy discrimination thresholds of Medipix3 technology allow spectral X-ray imaging. Different materials in an inspected sample could be then identified based on their spectral X-ray attenuation properties. Energy spectra could be measured typically from 5 keV upwards. The integrated Charge Summing Mode corrects for inter-pixel charge sharing, significantly improving spectral accuracy and the quality of per-pixel spectra.

Do you need to determine the material composition of your sample? Minerals, alloys, polymers, electronics, batteries, or pigments? Our cameras are based on cutting-edge single X-ray photon counting sensors, and each detected photon is processed individually. This approach also allows measuring the wavelength of photons. It brings unprecedented image quality and new possibilities, such as material-sensitive X-ray imaging. Moreover, our detectors enable fast and compact X-Ray Diffraction (XRD) and Crystallography solutions. XRD sample analysis is performed up to an order of magnitude faster than conventional systems. Spectral sensitivity provides a unique ability to inspect the sample surface and its interior (Energy dispersive XRD).

Cancer research, bio-mechanics, and drug testing are just a few examples of X-ray imaging contributing to biology and medicine research. New photon-counting detectors represent a severe advancement to these applications compared to previously used methods. The energy sensitivity of modern cameras opens better possibilities for identifying individual types of tissue and contrast agents. That has significant consequences in various industries, for example, cancer research, where the tumor tissue can be better distinguished from the healthy one.
