January 7, 2008 - 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), joining Acuson Corp., a Siemens company, Royal Philips Electronics and GE as a licensee of the technology.
RCT manages the THI technology for its partner, the University of Rochester in Rochester, NY. Seminal work in the early 1990s by P. Ted Christopher, Ph.D., at the University's Center for Biomedical Ultrasound resulted in a new mode of ultrasound imaging that has become an essential part of diagnostic ultrasound today. 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 sharper, higher-contrast image than that of the fundamental emitted frequency.
