This paper reports experimental results obtained from an 8]8 pixellated CZT detector provided by Imarad Imaging Systems. Three arbitrarily selected pixels were independently tested using c rays of di!erent energies. The signals from an anode pixel and the cathode were read out simultaneously. From the observations of the pulse waveforms from both the anode pixel and the cathode, the electron-in...

BACKGROUND Cadmium zinc telluride (CZT) solid-state detectors have been recently introduced in the field of nuclear medicine in cardiology and breast imaging. The aim of the current study was to evaluate the performance of the novel detectors (CZT) compared to that of the routine NaI(Tl) in bone scintigraphy. A dual-headed CZT-based camera dedicated originally to breast imaging has been used, a...

Cadmium Zinc Telluride (CZT) detectors enables high spatial resolution and detection efficiency are utilized for many gamma-ray X-ray spectroscopy applications. In this paper, we describe a stable bonding process report on the characterization of cross-strip CZT before after to flexible circuit. The utilizes gold stud polymer epoxy technique bond circuits two crystals form detector module in an...

This paper presents an alternative to conventional gamma camera. The proposed system is based on the combination of a new detection material – CZT and a new acquisition geometry – 1D detector with slat collimator. The slat collimator offers a better compromise to the usual sensitivity-resolution tradeoff. Solid-state detection offers significantly improved energy resolution. The combination of ...

The CCD analog transversal filter Is a tremendously cost-effective component In terms of its simplicity compared to equivalent diqltal hardware. In view of this, the chirp z-transform (CZT) algorithm for performing spectral analysis is ideally suited to ccn implementation because, in this algorithm, the bulk of the computation Is performed in a transversal filter. The CCD CZT has some performan...

Conventional explosive detection systems (EDS) based on X-ray technologies are using dual-energy radiography; they provide only a crude material characterization. Recently emerged semiconductors based X-ray detectors offer new capabilities in energy discrimination. This study is aiming at evaluating their interest for EDS. LETI-LDET laboratory has developed several pixellated CdTe/CZT detectors...
