United Imaging has installed its 4 cm uCT Atlas scanner at Russellville Hospital, a 49-bed acute care facility located in northwest Alabama.
This is United Imaging's first U.S. installation of the new 4 cm-version of the CT scanner, having just recently received U.S. Food and Drug Administration 510(k) clearance.
The uCT Atlas features z-axis coverage up to 16 cm, with an ultra-wide 82 cm bore and a 700-lb table weight capacity. The scanner also includes an integrated uAI Vision 3D camera to enable an AI-empowered workflow for operational efficiencies; a 0.25-second gantry rotation; and 60 kVp low-dose scanning, according to the vendor.
![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)
