RCT Licenses Ultrasound Tissue Harmonic Imaging Technology to Philips

TUCSON, Ariz.--(HSMN NewsFeed)--Research Corporation Technologies (RCT) has granted Royal Philips Electronics and its affiliates, including the ultrasound business of Philips Medical Systems, a nonexclusive license to pioneering patents owned by RCT that broadly cover ultrasound tissue harmonic imaging (THI).

Tucson-based RCT manages the THI technology for its partner, the University of Rochester in Rochester, New York. Seminal work in the early 1990s by 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, better-contrast image than that of the fundamental emitted frequency.

Royal Philips Electronics of the Netherlands (NYSE: PHG, AEX: PHI) is a global leader in healthcare, lifestyle and technology, delivering products, services and solutions through the brand promise of "sense and simplicity." Headquartered in the Netherlands, Philips employs approximately 124,300 employees in more than 60 countries worldwide. With sales of EUR 27 billion in 2006, the company is a market leader in medical diagnostic imaging and patient monitoring systems, energy efficient lighting solutions, personal care and home appliances, as well as consumer electronics.

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 pending.

Philips joins Acuson Corporation, a Siemens company, as a licensee of the tissue harmonic imaging technology. RCT continues its efforts to license the technology broadly to the ultrasound industry.

The Rochester Center for Biomedical Ultrasound ( unites the university's medical and engineering communities. Center researchers investigate use of very high-frequency sound waves in medical diagnosis and treatment, and other medical imaging applications.

Research Corporation Technologies ( is a technology investment and management company that provides early-stage funding and development for promising biomedical companies and technologies from universities and research institutions worldwide. RCT carries on a vision of nearly 100 years that chAmpions the commercialization of academic innovation. RCT has assets of more than $300 million to advance technology development through venture investment, partnerships and special licensing programs.
