(Booth 3005) Columbia, MO-based Meta Imaging Solutions will showcase its Chrysalis displacement system for CT exams, designed to reduce radiation exposure to breast tissue during coronary CT angiography or CT scans of the abdomen.
Chrysalis is constructed of soft, padded vinyl that encircles the patient, and it contains a system of interconnected components to fit patients of all sizes. Use of the Chrysalis system can be an effective way to reduce dose while improving image quality due to decreased tissue in the scan plane, according to the company.
A randomized trial showed median dose reductions of 88% in the periareolar region and 95% in the upper quadrants of breast tissue, while yielding improved image quality in patients who have larger breasts, according to the company.
The device has received U.S. Food and Drug Administration 510(k) clearance.
![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)
