Energy Selecting X-Ray Imaging with Highflux CdZnTe Linear Array Detectors

Le résumé fourni par la source

Recently, we developed sub-keV energy resolution CZT linear array detectors based on high-flux HF-CZT material. The detectors, designed for energy resolved X-ray imaging, allow high spatial$(500 \mu ~\mathrm{m})$and energy ($<0.7 \text{keV}$FWHM at 60 keV) resolution. In this work, we will present the results from X-ray imaging measurements with particular emphasis to the benefits of the excellent energy resolution of the detectors in contaminant detection. The effects of charge sharing and energy-resolved techniques on contrast-to-noise ratio (CNR) enhancements are investigated. Moreover, the benefits of a new energy-resolved X-ray imaging approach, termed window-based energy selecting, in the detection of low- and high-density contaminants are also shown. The activities are in the framework of Italian research projects, planning the development of X-ray scanners for contaminant detection in food industry.
