Monte Carlo modelling of a compact CZT-based gamma camera with application to 177Lu imaging

Background Semiconductor gamma-camera systems based on cadmium zinc telluride (CZT) detectors present new challenges due to an energy-response that includes effects of low-energy tailing. In

Design studies of a CZT-based detector combined with a pixel-geometry-matching collimator for SPECT imaging

From the simulation studies, it is found that such a camera using rectangular holes has promising imaging characteristics in terms of spatial resolution, detection efficiency, and energy resolution.

Simulation of 3D Sensors

The Large Hadron Collider (LHC) at CERN has the highest energy and luminosity in the world. Radiation hardness is then a critical requirement for the inner tracker design. The inner tracker is

Fabrication and test of pixelated CZT detectors with different pixel pitches and thicknesses

The main methods grown Cadmium Zinc Telluride (CZT) crystals with high yield and excellent homogeneity are Modified Horizontal Bridgman (MHB) and High Pressure Bridgman (HPB) processes, respectively.

Design of programmable gain linear pulse amplifier based on energy spectrum analysis

The multichannel pulse amplitude analyzer as an important component of the spectrum measuring instrument, the performance of the linear pulse amplifier directly affects the final results of the



CZT detectors with 3D readout for gamma-ray spectroscopy and imaging

The technique is described, results of modeling and tests are presented, and Compton kinematic analysis can identify the initial interaction site in most cases as well as constrain the incident gamma-ray direction.

Development of the TIGRE Compton telescope for intermediate-energy gamma-ray astronomy

Gamma-ray observations in the low and medium energy range (0.1-100 MeV) with sufficiently sensitive telescopes will provide unique insights into many outstanding high-energy astrophysics questions.

We report progress in the study of thick CZT strip detectors for 3-d imaging and spectroscopy and discuss two approaches to device design. Unlike double-sided strip detectors, these devices feature

3-D position sensitive CdZnTe spectrometer performance using third generation VAS/TAT readout electronics

Three-dimensional (3-D) position-sensitive CdZnTe (CZT) gamma-ray spectrometers employing new VAS3.1/TAT3 ASIC readouts were developed and tested. Each spectrometer is a 1.5 /spl times/ 1.5 /spl

A method is given for computing the instantaneous current induced in neighboring conductors by a given specified motion of electrons. The method is based on the repeated use of a simple equation

Currents to Conductors Induced by a Moving Point Charge

General expressions are derived for the currents which flow in the external circuit connecting a system of conductors when a point charge is moving among the conductors. The results are applied to
