Siemens Healthineers has received U.S. Food and Drug Administration (FDA) clearance for two CT systems in the company's go. product family.
The 64-slice Somatom go.Sim and 128-slice Somatom go.Open Pro are designed for radiation therapy planning. The Somatom go. platform features hardware and software components such as patient marking lasers and automated quality assurance to limit potential errors and reduce time to treatment. The scanners have 85-cm bores to accommodate positioning accessories and to improve patient comfort.
In addition, Somatom go.Open Pro's Direct Intelligent 4D (Direct i4D) technology is designed to adapt image acquisition to patient breathing in real-time to reduce artifacts and variations in images to potentially decrease target margins and spare healthy tissue.
![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)
