Toshiba America Medical Systems of Tustin, CA, has debuted cardiac software upgrades for its Aquilion One and Aquilion Premium CT systems.
The new cardiac CT software package is designed to reduce radiation exposure while maintaining image quality. It includes Toshiba's new one-beat prospective reconstruction protocol, which shortens the interval window and reduces radiation exposure time; real-time beat control, which calculates the running real-time average of the heart rate to predict the next heartbeat for a more accurately timed scan; and SureStart, which can determine contrast uptake time for a more accurate image, according to Toshiba.

![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)
