(Booth 6237) Image Analysis of Columbia, KY, plans to show a new automated CT bone densitometry system at this year's RSNA meeting.
QCT DXAView Hip Application uses conventional quantitative CT volumetric images, acquired with calcium hydroxyapatite phantoms, to create 2D bone mineral density (BMD) measurements of the hip that are comparable to conventional dual-energy x-ray absorptiometry, according to the company. QCT DXAView's automatic image-processing methods include segmentations, calibration, coordinate system, rotations, region-of-interest placements, and BMD measurements.
The company also will highlight a new calibration phantom device, INTable Calibration, designed to improve CT BMD technology. INTable's pad replaces a conventional couch pad and can remain in place for all CT studies. The device can be used for calcium scoring and lumbar, thoracic spine, and hip BMD without the need for patient or phantom repositioning, according to Image Analysis.
![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)
