Toshiba America Medical Systems has installed its first 640-slice Aquilion One Vision Edition CT scanner in the state of Oregon.
The new scanner at Oregon Health and Science University in Portland will help improve the facility's diagnostic capabilities for trauma, cardiac, stroke, and pediatric patients, the firm said.
The system is capable of generating 0.5-mm slices with a gantry rotation of 0.275 seconds. Its 16 cm of coverage is capable of imaging entire organs, such as the heart and brain, in a single rotation. The scanner also features a large 78-cm bore and Toshiba's adaptive iterative dose reduction (AIDR) 3D software.
![Axial images from unenhanced calcium score cardiac CT (left) and curved planar reformation images from CT angiography (right) show that higher long-term exposure to air pollution is associated with greater coronary artery calcium and more obstructive coronary artery disease (CAD). Top row: Images in a 68-year-old male patient with higher 10-year mean ambient air pollution exposure (7.9 μg/m3 for particulate matter measuring ≤2.5 μm in diameter [PM2.5] and 17.4 parts per billion [ppb] for NO2) with extensive CAD (coronary artery calcium score [CACS] >1,000 and obstructive CAD [≥70% diameter stenosis]). Bottom row: Images in a 57-year-old female patient with lower 10-year mean ambient air pollution exposure (6.3 μg/m3 for PM2.5 and 4.6 ppb for NO2) with no CAD (CACS = 0 and no obstructive stenosis).](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2026/06/hanneman.r6SMLzkezo.png?auto=format%2Ccompress&dpr=2&fit=crop&h=167&q=70&w=250)
