The purpose of this study was to investigate if a novel parameter, the stress-to-rest ratio of the signal-to-noise ratio (RSNR) obtained with a cadmium zinc telluride (CZT) SPECT scanner, could be used to distinguish triple-vessel disease (TVD) patients. Methods. One hundred and two patients with suspected coronary artery disease were retrospectively involved. Each subject underwent a Tl-201 SP...

Food x-ray inspection systems are designed to detect unwanted physical contaminants in packaged food maintain a high level of safety for consumers. Modern day often utilize line scan sensors these but limited single or dual energies. However, by using photon counting detector (PCD), new generation capable acquiring images at more than two energy bins could improve discrimination between low den...

Abstract The article presents the method of using a modified acoustic miss distance indicator applied together with set controlled aerial target imitators (ZSMCP) Jaskółka “Swallow” operated in Polish Armed Forces. described enables implementation controlling and testing new CZT inspect technical condition these, which are still operated.

Emergency room evaluations of patients presenting with chest pain continue to rise, and these evaluations which often include cardiac imaging, are an increasing area of resource utilization in the current health system. Myocardial perfusion imaging from the emergency department remains a vital component of the diagnosis or exclusion of coronary artery disease as the etiology of chest pain. Rece...

Tandem solar cells consisting of high bandgap cadmium telluride alloys atop crystalline silicon have potential for high efficiencies exceeding the Shockley-Queisser limit. However, experimental results have fallen well below this goal significantly because of non-ideal current matching and light trapping. In this work, we simulate cadmium zinc telluride (CZT) and crystalline silicon (c-Si) tand...

Urban expansion has significant effects on forest loss and fragmentation. Previous studies mostly focused on how the amount of developed land affected forest loss and fragmentation, but neglected the impacts of its spatial pattern. This paper examines the effects of both the amount and spatial pattern of urban expansion on forest loss and fragmentation. We conducted a comparison study in the si...

The Discovery NM530 is a new generation of SPECT cameras equipped with semiconductor cadmium-zinctelluride (CZT) detector technology. It provides a shorter scan time and reduces the patient’s radiation exposure wthout loss of image quality compared with the conventional Anger camera. Combined supine and prone imaging with the Discovery NM530c is useful for reducing the false-positive rate in th...
