Dual Source, Dual Energy, Dual Diagnosis
Wiener klinisches Magazin, 2010Die Dual Source Computer Tomographie vereint zwei Rontgenrohren in einem Gerat. Durch den gleichzeitigen Einsatz von zwei Rohren an einem Patienten ergeben sich zwei Einsatzmoglichkeiten. Zum Einen konnen beide Rontgenrohren unterschiedliche Teile des Patienten untersuchen und die Daten dann zusammensetzen.

A unique function of the SOMATOM Definition Dual Source CT system is its capacity to operate each x-ray tube at different kV and mA settings. While dual-energy CT was originally developed and evaluated 20 years ago, technical limitations of the CT scanners and post processing software at that time prevented the development of routine clinical ...

Dual-Energy Dividing Mammography
2010The cancers exhibit a higher effective atomic number than the normal tissue The aim of this study was to improve early detection of microcalcifications, which are the earliest indicators of breast cancer, and to get a better definition of the cancer boundary on the base of visualization of an effective atomic number distribution Dual-energy subtraction

Dual Energy: Tendons and Cartilage
2008The introduction of multi-detector row computed tomography (MDCT) has lead to remarkable advances in the field of musculoskeletal imaging. MDCT enables the acquisition of isotropic data sets in high-spatial-resolution, from which multiplanar reformatted images can be calculated in any desired plane.

Technical Advancements in Dual Energy
2015There is no question that technological development and innovation in CT imaging proceeds at a rapid pace. New techniques for dual-energy image acquisition are constantly being developed and current technologies are being refined. The demands of the field of cardiac radiology are such that improvements in image quality as well as a push towards using ...

In dual-energy CT, two CT datasets are acquired at different photon energy spectra. Because chemical elements vary in their attenuation properties at different photon energies, this allows to analyze the chemical composition of the imaged tissues and to extract or suppress individual chemical components.

Aortic aneurysms are a common pathology, with the potential risk of rupture.1 Aneurysms can be differentiated into true aneurysms, which involve all three layers of the vessel wall (intima, media and adventitia), false aneurysms (pseudoaneurysms), where a collection of blood communicates with the arterial lumen but is not surrounded by normal vessel ...
