" meld with computer - aided machinery , it also put up us the opportunity to create a reproduction with a high-pitched degree of truth . "
A 3-D Model
The CT image were put into range - processing software called OsiriX , which created a flick display a3 - D modelof the violin . show here is a frame from OsiriX.
Carving a Violin
