A system for dual-energy radiography
The British Journal of Radiology, 1983A system has been developed and theoretically analysed for the generation of chemical information from conventional radiography. A specially modified cassette has enabled dual-energy radiographs to be taken during a single exposure. A simple theoretical model has demonstrated that the concept of an optical density "standardised" to the local ...

Interest in dual-energy CT (DECT) for evaluating the myocardial blood supply, as an addition to coronary artery assessment, is increasing. Although it is still in the early clinical phase, assessment of myocardial ischemia and infarction by DECT constitutes a promising step toward comprehensive evaluation of coronary artery disease with a single ...

Thoracic Applications of Dual Energy
Radiologic Clinics of North America, 2010Recent technological advances in multidetector computed tomography (CT) have led to the introduction of dual-source CT, which allows acquisition of CT data at the same energy or at 2 distinct tube voltage settings during a single acquisition. The advantage of the former is improvement of temporal resolution, whereas the latter offers new options for CT

A Technique for Simultaneous Dual Energy S
Journal of Computer Assisted Tomography, 1979A method of deriving simultaneous dual energy scans on a conventional EMI CT5005 scanner is described. The only change that has to be made to the scanner involves the detector collimator where alternate slits are covered by a thin metal foil. The detector readings from the covered and uncovered slits are separated by software before picture processing ...

Dual energy cardiac computed tomography
Minerva Cardiology and Angiology, 2017Conventional single energy CT suffers from technical limitations related to the polychromatic nature of X-rays. Dual energy cardiac CT (DECT) shows promise to attenuate and even overcome some of these limitations, and might broaden the scope of patients eligible for cardiac CT towards the inclusion of higher risk patients.

Dual-Energy CT: Oncologic Applications
American Journal of Roentgenology, 2012Dual-energy CT (DECT) is an innovative imaging technique that operates on the basic principle of application of two distinct energy settings that make the transition from CT attenuation-based imaging to material-specific or spectral imaging. The purpose of this review is to describe the use of DECT in oncology.Applications of DECT in clinical practice ...

Abdominal Imaging, 2013
Although conceived of in the 1970s, practical use of dual-energy CT in the clinical setting did not come to fruition until 2006, and since that time an ever expanding exploration of the technology has been underway. This article will discuss technical aspects of the two commercially available CT scanners, review the recent literature, and provide an ...

Dual-energy computed tomography (DE-CT) uses polyenergetic X-rays at 100- and 140-kVp tube energy, and generates 120-kVp composite images that are referred to as polyenergetic images (PEIs). Moreover, DE-CT can produce monoenergetic images (MEIs) at any effective energy level.

The dual sustainability of wind energy
Renewable and Sustainable Energy Reviews, 2009Abstract Academics, practitioners, and policy makers continue to debate the benefits and costs of alternative sources of energy. Environmental and economic concerns have yet to be fully reconciled. One view is that decisions that incorporate both society's concern with the environment and investors’ desire for shareholder value maximization are more ...

The dual energy supply of eukaryotic cells
2022The regeneration of tissue damage is possible because our cells have a dual-energy supply system and can ensure tissue regeneration without O2. The publication summarizes the defining elements of the structures responsible for energy transformation (SET), specifically, the hypothetical ADP-producing unit, the SET of anaerobic glycolysis (SET-AG), and ...
