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

RCT of Tucson, Ariz., manages the THI technology for its partner, the University of Rochester in Rochester, N.Y. The work of 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 harmonic response of native tissue to a propagated ultrasound beam could be employed to produce a sharper, higher-contrast image than that of the fundamental emitted frequency.

RCT received the U.S. Patents for THI in March 2001, February 2006 and September 2006. Two other U.S. patents are currently pending.

GE joins Philips and Siemens as a licensee of the THI technology, according to RCT.
