Chronos Imaging has shipped its 100th CT x-ray tube, two months after acquiring an Aurora, IL, manufacturing plant from Philips Healthcare.
Philips sold the facility to Chronos in February of this year, with Chronos agreeing to continue to produce CT tubes for Philips and sell them under the Dunlee name. Dunlee is a Philips subsidiary that previously occupied the plant.
Chronos also said it has received its U.S. Food and Drug Administration (FDA) license; additional local, state, and federal licenses; and its ISO 13485 medical device certification as part of its regulatory program.
![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)
