ct scans re-create 307-year-old violin

A few years ago, doctor.
Steven Sirr decided to combine his two passions: a ct scan and a violin.
But not just the violin. a 307-year-
One of the most precious instruments in the world, old Stradivaris.
Sirr worked with a number of violin manufacturers to build their own Stradivarius using scanning technology.
It all started with a gun.
\"I supervised three residents at the county hospital where I worked in Minneapolis, Minnesota.
It was a very boring weekend so I brought the violin in to practice, \"Sirr said in an interview with NPR\'s Guy Raz.
\"A shooting victim entered the CT scanner.
One of the residents slammed on the door and wanted me to have a look at the CT scan, and I took the violin to the scanner and put it on the table next to the scanner.
So when the patient does CT
I turned around and saw my violin and scanned it.
Sirr said he was surprised by the anatomy.
\"But in the end, he wanted to scan a violin worth millions of dollars and convince officials at the Library of Congress to allow him to use their violin.
It even has the original label in Antonio stravari inside the body.
\"The Library took part in a two-game
Last summer we had a week of project in Oberlin, Ohio, when we were able to do CT-
Scan the original Betts violin made at 1704, \"said Sirr.
After scanning the violin, Sirr handed the file to violin manufacturer Steve Roso, who made a CNC machine for carving the violin.
\"I took the file directly from the CT scanner and put it into a table that his computer can read,\" Sirr said . \". \"Then, with [Rossow\'s]
The machine, he was actually able to carve out the front and back plates of the stradivarus violin and sidepieces with extremely high precision, as well as the neck and reel of the 1704 stradivarus.
\"Of course, no matter how many scans you do, certain aspects of Stradivarius cannot be captured.
\"According to the quality of the wood, each violin is completely different,\" Sirr said . \".
\"We are trying to match the density of wood from CT scans.
We look at the original texture pattern and try to get a similar one.
Sirr said he hopes to bring the technology and violin to market one day, \"especially the latest Strad sold last summer for nearly $16 million, this is far beyond the scope of any modern life violin manufacturer.
We think they sound great.
We used the violin for two weeks in Oberlin, Ohio, so we also knew what the original sound was like.
