X-ray diffraction imaging system for the detection of illicit substances using pixelated CZT-detectors
The use of energy-dispersive X-ray diffraction (XRD) in security screening applications allows for highest detection and lowest false-alarm rates. Expand
Mark-sweep or copying?: a "best of both worlds" algorithm and a hardware-supported real-time implementation
In this paper, we introduce a novel mark-compact algorithm that combines the elegance and simplicity of Baker's copying algorithm with the memory efficiency of mark-sweep algorithms. Expand
NuVISION: a Portable Multimode Gamma Camera based on HiSPECT Imaging Module
We have recently developed NuVISION, a portable gamma camera based on CZT. Expand
Studying Spatial Resolution of CZT Detectors Using Sub-Pixel Positioning for SPECT
CZT detectors are the basic building block of a variety of new SPECT systems. Their modularity allows adapting system architecture to specific applications such as cardiac, breast, brain or smallExpand
An autonomous CZT module for X-ray diffraction imaging
We present the development of a CZT-based detection module dedicated to X-ray diffraction imaging. This kind of application requires a good energy and spatial resolution in order to resolve BraggExpand
Design and Evaluation of a Burst Assembly Unit for Optical Burst Switching on a Network Processor
Optical Burst Switching (OBS) has been proposed in the late 1990s as a novel photonic network architecture directed towards efficient transport of IP traffic by optimally combining electronics and optics. Expand
Exploiting the efficiency of generational algorithms for hardware-supported real-time garbage collection
Generational garbage collectors are more efficient than their non-generational counterparts. Unfortunately, however, generational algorithms require both write barriers and write barrier handlers andExpand
Evaluation of a CZT gamma-ray detection module concept for SPECT
CZT detectors are the basic building block of a variety of new SPECT systems. Expand

Un objet de l'invention est un procede de calibration d'un detecteur de rayonnement ionisant, visant a determiner un facteur de correction afin d'etablir une correspondance amplitude - energie. UnExpand
A 256 energy bin spectrum X-ray photon-counting image sensor providing 8Mcounts/s/pixel and on-chip charge sharing, charge induction and pile-up corrections
A new pixel architecture for spectral imaging is presented, exhibiting a 256 bin spectrum per pixel in a single image duration, up to two orders of magnitude higher than previous works. Expand
