Tailor your CT system to meet your clinical needs, now or in the future. Volumetric and helical Dual Energy scans provide advanced tissue characterization

The innovative X-ray tube concept in the new CT scanner, enables simultaneous imaging at two different energy levels for the first time in single source computed tomography., With the new version of the Somatom Definition Edge, Siemens Dual-energy CT provides information about how substances behave at different energies, the ability to generate virtual unenhanced datasets, and improved detection of iodine-containing substances on low-energy images. Purpose: Dual-energy CT (DECT) has been shown to derive stopping power ratio (SPR) map with higher accuracy than conventional single energy CT (SECT) by obtaining the energy dependence of photon 2008-04-17 · Dual-energy CT-based material extraction could have limited clinical applications because of the complication of patient movement between the two CT scans which could cause the two different kVp images to mis-align. However, Kalender et al developed a CT scanner with a prototype apparatus for rapid kVp switching. Fig. 4.1 Schematics of rapid kV switching dual-energy CT (DECT) imaging (a) and single-energy CT (SECT) imaging (b) on a GE CT750 HD scanner. In a DECT scan, projections are acquired at 140 kV (orange solid line) and 80 kV (green dashed like) alternatively at every 0.2 milliseconds.

CHALLENGES WITH SINGLE ENERGY CT Tissue characterization Lesion detection (small lesion) Image noise and quality at low kV scanning Complex scanning protocols Multiphase imaging Radiation dose 3 The term “dual-energy CT,” or “DECT,” refers to CT that uses two photon spectra; therefore, DECT is sometimes also referred to as “spectral CT.” In clinical practice today, two different spectra are generated either by switching the voltage of one x-ray tube or by running two tubes at different voltages, and spectral information is gained from two absorption measurements with Material decomposition in dual-energy computed tomography separates high-Z elements from iodine, identifying potential contrast media tailored for dual contrast medium examinations Tobias Fält , Marcus Söderberg , Johan Wasselius & Peter Leander , 2015 , I: Journal of Computer Assisted Tomography.
