All peripheral CTA scans were performed using 128-slice du-al-source CT (Definition FLASH, Siemens Medical Solutions, Forchheim, Germany); 100 kVp was used in both protocols. CT scan began 25
Each detector contains 64 detector rows, each of which is 0.6 mm wide. Using the z-flying focal spot technique, two 64-channel 0.6 mm measurements are combined to create 128 “slices” of projection data along the z axis. The shortest gantry rotation time is 0.28 s.
Subsequently, 2007 to 2008 saw 128-, 256-, 320-slice, and dual-source CT scanners with z-coverage of up to 16 cm. By 2012, Toshiba medical (now Canon Medical System) introduced a 640-slices CT scanner, which was digitally enhanced from 320-slice to 640-slice with double-slice technology and coneXact™ reconstruction algorithm, though the z

Overview: Gemstone Spectral Imaging – the first quantitative dual-energy CT on the market.Neuroimaging – the Discovery CT750 HD ensures ample coverage to perform perfusion studies of the entire brain.Clarity without compromise.You and your patients continue to demand lower dose — but not at the expense of diagnostic image quality.
In this case, the agreement is always below 3% for abdomen scans and 1.0% for head examinations. This result implies that the radiation dose supplied by the 16-slice computed tomography (CT) system was in good agreement with the international dose reference level and we observed something different.
