A number of research groups have been investigating the use of dedicated breast computerized tomography (CT). Preliminary results have been encouraging, suggesting an improved visualization of masses on breast CT as compared to conventional mammography. Nonetheless, there are many challenges to overcome before breast CT can become a routine clinical reality. One potential improvement over curre...

Cadmium Zinc Telluride (CZT) achieves excellent spatial resolution and good energy resolution over the broad energy range from several keV into the MeV energy range. In this paper we present the results of a systematic study of the performance of CZT detectors manufacturered by Orbotech (before IMARAD) depending on surface preparation, contact materials and contact deposition. The standard Orbo...

In the past, various virtual Frisch-grid designs have been proposed for cadmium zinc telluride (CZT) and other compound semiconductor detectors. These include three-terminal, semi-spherical, CAPture, Frisch-ring, capacitive Frisch-grid and pixel devices (along with their modifications). Among them, the Frisch-grid design employing a noncontacting ring extended over the entire side surfaces of p...

A CZT Compton Camera (CCC) is being built using two three-dimensional (3-D) position-sensitive CZT detectors. Expected system performance was analyzed by analytical and Monte Carlo approaches. Based on the measurement of detector energy and position resolution, the expected angular resolution is &33 and &23 for a $303 FOV for 511 keV and 1 MeV c-rays, respectively. The intrinsic e$ciency for a ...

The Image watermarking assumes a vital part in different applications like secure information transmission and Image copyright assurance. Watermarking method can be isolated into spatial and change space technique. A watermarking method is said to be idealize on the off chance that it works better in case of different assaults. This paper presents different methods of picture watermarking. The ...

The Community Z Tools (CZT) project is an open-source Java framework for building formal methods tools for Z and Z dialects. It also includes a set of tools for parsing, typechecking, transforming and printing standard Z specifications in LTEX, Unicode or XML formats. This paper gives an overview of the CZT framework, including an introduction to its visitor design pattern that makes it possibl...

Detection of X- and gamma-rays is essential to a wide range applications from medical imaging high energy physics, astronomy, homeland security. Cadmium zinc telluride (CZT) the most widely used material for room-temperature detector has been fulfilling requirements growing detection demands over last three decades. However, CZT still suffers presence density performance-limiting defects, such ...

Abstract Purpose of Review The purpose this review is to provide a summary on the status art simultaneous perfusion-innervation imaging by CZT-SPECT and clarify its potential applications in clinical practice. Recent Findings Introduction CZT cameras represented critical breakthrough nuclear cardiology. Although it has been demonstrated that cardiac innervation may be easily assessed CZT-SPECT,...

UNLABELLED Differences in the performance of cadmium-zinc-telluride (CZT) cameras or collimation systems that have recently been commercialized for myocardial SPECT remain unclear. In the present study, the performance of 3 of these systems was compared by a comprehensive analysis of phantom and human SPECT images. METHODS We evaluated the Discovery NM 530c and DSPECT CZT cameras, as well as ...
