Research Corporation Technologies (RCT) has granted Biosound Esaote a nonexclusive license to pioneering patents owned by RCT that broadly cover ultrasound tissue harmonic imaging (THI).

The Tucson-based RCT manages the THI technology for its partner, the University of Rochester in Rochester, N.Y. Seminal work in the early 1990s by P. Ted Christopher, PhD, at the University's Center for Biomedical Ultrasound resulted in a new mode of ultrasound imaging.
Christopher's invention showed that the second and higher-order harmonic response of native tissue to a propagated ultrasound beam could be employed to produce a higher-contrast image than that of the fundamental emitted frequency.

RCT received U.S. Patent No. 7,104,956, in September 2006; U.S. Patent No. 7,004,905 in February 2006; and U.S. Patent No. 6,206,833 in March 2001. Two other U.S. patents are currently pending.

Biosound of Indianapolis, is a medical imaging company that specializes in ultrasound systems. The company joins Acuson, a Siemens company, Philips Healthcare and GE Healthcare, as a licensee of the THI technology.
