Product description
The large area imaging detector WidePIX CHROMATIC is composed of Medipix2 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 WidePIX CHROMATIC is suitable for CT scanners, because it combines:
