A Louisville, KY, violin maker uses CT images to help him craft his award-winning instruments, according to a May 24 report posted on Spectrum News 1.
Former software engineer turned luthier George Yu examines CT scans of Amati and other virtuoso violins to "learn the patterns and shapes to craft his own unique style," Spectrum reported. The Amatis were a clan of violin makers in Cremona, Italy, between 1538 and 1740.
Yu graduated from the Violin Making School of America in Salt Lake City in 1999; his instruments have won awards and sell for $25,000, according to Spectrum News 1.
![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)
