CT Technology Update: Dual-Energy Duel — Manufacturers Show Their New Features at RSNA 2014 By Keith Loria Radiology Today Vol. 16 No. 4 P. 24 GE Healthcare Systems | GE Healthcare (United States) •“CT can now be performed routinely in DE Mode without additional dose or compromise in image quality…” Invest Radiol 2010; 45: 347 •“Dual Energy CT is equivalent and can be used for routine diagnostic purposes….” AJNR 2011; 32:1994 •“Dual energy CT is now the routine for all my abdomen and pelvis studies….” 2021-04-22 · “The idea behind dual-energy CT or spectral CT is that different materials or the attenuation of different materials behaves differently when you look at different energies,” Ulzheimer explains. Acknowledging the usefulness of scanners utilizing different energy levels, imaging manufacturers have begun developing spectral CT advancements for their CT offerings. Courtesy of Uri Shreter, GE Healthcare Rapid kVp switching Dual energy CT • Requires fast generator and detectors • Dose allocation controlled by dwell time • Difficult to switch filters Data acquisition implementations • Sequential scans at different kVp motion sensitivity > scan time • Two sources at 90º on the same gantry GEでは，2009年頃よりfast kVp switching方式によるdual energy撮影“Gemstone Spectral Imaging（GSI）”が，ガーネット検出器を搭載したCTで可能となった。 そして2017年，「Revolution CT」でのdual energy撮影である“GSI Xtream”が日本国内でも稼働を開始し，2018年1月現在約40施設で使用されている。 Dual-energy CT (DECT) refers to the new simultaneous acquisition of low- and high-voltage CT data.

2020-01-17 · All radiographic examinations were performed using a single source dual-energy CT system (Discovery CT750HD, GE Healthcare, Milwaukee, WI, USA) with 64 detectors and a scan field of view of 32 cm. The tube voltage of the system is switched extremely rapidly, in less than 0.03 μs, between the two different energy levels i.e. 80 kVp and 140 kVp, both at 550 mA.
