Dr. Robert Howe, a reproductive endocrinologist in East Longmeadow, Massachusetts, says his medical practice showed him how computerized tomography could make precise 3-D images of body parts. Howe, who is also a doctoral student in music theory and history at UConn, last year brought his idea to music theory professor Richard Bass, who contacted Sina Shahbazmohamadi, an engineer and the school's director for advanced 3-D imaging. Together, they have developed a process for using CT scanning technology not only to make images of those instruments but also to print 3-D copies of parts that will allow more of them to be played. The CT scanning alone has yielded exciting results, including images that show the construction of an 18th-century English horn was much more complicated than experts originally thought. Because nobody would allow one of the rare and delicate instruments to be cut open, experts couldn't see the intricate set of bores and wooden pins used to hold it together, Howe said.
