Toshiba America Medical Systems has upgraded an Aquilion One CT scanner at Memorial University Medical Center with its new metal-artifact reduction technology.
The scanner at Memorial's Savannah, GA, location has been upgraded with Toshiba's single-energy metal artifact reduction (SEMAR) technology, which minimizes streak artifacts from metal implants, Toshiba said.
Memorial University Medical Center includes its flagship hospital, a 654-bed academic medical center; primary and specialty physician networks; a medical education program; business and industry services; and NurseOne, a 24-hour call center, the company said. It is a two-state healthcare organization serving a 35-county area in southeast Georgia and southern South Carolina.
![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)
