A team of radiologists has found a novel application for a high-end CAT scan: violin making. Not just any violin, but a replica of a 307-year-old model from the famous Italian violin maker Antonio Stradivari. After taking more than 1,000 CAT scan images of the instrument that revealed details, such as wood density and age distress, the group converted them into 3D computer-aided design files and went to work. A machine then automatically carved sections of the violin based on the CAD data. As for the sound, radiologist Steven Sirr called it "amazingly similar" to the original.
