The Aquilion One Vision Edition 640-slice computed tomography (CT) scanner is equipped with a gantry rotation of 0.275 seconds, a 100 kw generator and 320 detector rows (640 unique slices) covering 16 cm in a single rotation, with the industry’s thinnest slices at 500 microns (0.5 mm). The system can accommodate larger patients with its 78 cm bore and fast rotation, including bariatric and patients with high heart rates.

Aquilion One Vision Edition also includes Toshiba’s third-generation iterative dose reconstruction software, AIDR 3-D, which incorporates significant system enhancements by reducing radiation dose compared with conventional scanning.

Studies at the National Institutes of Health, where the system is installed, on CT angiography found coronary scans could be completed in 0.0137 seconds and with less than 1 mSv of dose for an average sized patient. This less-than-a-second scan time allows for single-beat cardiac cycle scans. The 16 cm coverage area also means one scan can acquire the whole volume of the heart, so no image stitching is required.

The couch has a 660 lb capacity.

The system was cleared by the U.S. Food and Drug Administration (FDA) in September 2012
