X-ray diffraction imaging system for the detection of illicit substances using pixelated CZT-detectors
TLDR
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
TLDR
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
TLDR
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
TLDR
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
TLDR
CZT detectors are the basic building block of a variety of new SPECT systems. Expand
method for calibrating an ionizing radiation detector device and associated
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
TLDR
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
