Samsung NeuroLogica has launched its Doro QR3 XTom intraoperative skull clamp, which supports patient positioning for its OmniTom mobile CT scanner during surgery, at RSNA 2019.
The device aids the 16-slice scanner's high image quality and 40-cm bore circumference to deliver a large field-of-view. The clamp, with radiolucent extension arms, attaches to an imaging or surgical table through a park-bench mount and the table's side rail. Doro's ultrawide quick rail accommodates brain tissue retractor systems and has two interfaces for image-guided brain navigation systems. The device dismantles easily to simplify disinfection, the firm said.
![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)
