CdZnTe detector in diagnostic x-ray spectroscopy.
A method to utilize CdZnTe (CZT) detectors in diagnostic x-ray spectroscopy is described in this article. Spectral distortion due to transmission of primary x rays, the escape of cadmium- and tellurium-K fluorescent x rays, and tailing was severe in measured x-ray spectra. Therefore, correction for the distortion was performed with the stripping method using response functions. The response fun...
متن کاملCdZnTe strip detector SPECT imaging with a slit collimator.
In this paper, we propose a CdZnTe rotating and spinning gamma camera attached with a slit collimator. This imaging system acquires convergent planar integrals of a radioactive distribution. Two analytical image reconstruction algorithms are proposed. Preliminary phantom studies show that our small CdZnTe camera with a slit collimator outperforms a larger NaI(Tl) camera with a pinhole collimato...
متن کاملSimulation of a Neutron Detector for Real Time Imaging Applications
Monte Carlo Method is used to simulate a double layer gadolinium-amorphous silicon thermal neutron detector. The detector fabricated in pixel array configuration has various applications including neutron imaging. According to the simulation results, a detector consisting of a gadolinium (Gd) film with thickness of 2-4 ~m, sandwiched properly with two layers of sufficiently thick (-30 ?µm) hydr...
متن کاملMEASUREMENT OF DIAGNOSTIC X-RAY SPECTRA USING CdZnTe DETECTOR
INTRODUCTION We directly measured diagnostic X-ray photon spectra produced by a single-phase 2-pulse diagnostic X-ray unit driven at 50 to 100 kV and a few mA(1), a mammographic X-ray unit at 25 to 32 kV and 3 times of 80 mAs(2) and an X-ray computed tomography (CT) scanner at 120 kV and 3 mA(3) have been analyzed. Since detected spectra were distorted by the response of CdZnTe(CZT) detector an...
متن کامل2D/3D Etching and Deposition Simulation Tools Implemented with a General TCAD Geometry Server
Implementation and validation of 2D and 3D etching and deposition simulators using a general TCAD geometry server with both the boundary and level-set representation is performed. Advantages of our approach include not only enhanced functionalities such as accurate and robust boundary movement and smoothing, but also well-defined procedural interface for facile inter-tool communication. Accurac...
