US Patent Granted for PET Depth of Interaction Technology

Zecotek Granted U.S. Patent for Depth of Interaction Technology for Advanced Positron Emission Tomography Detector Assemblies

Singapore, July 7, 2011 – Zecotek Photonics Inc. (TSX-V: ZMS; Frankfurt: W1I), a developer of leading-edge photonics technologies for medical, industrial and scientific markets, today announced that patent number 7,956,331 B2 has been granted by the U.S. Patent and Trademark Office for a Depth of Interaction technology, developed to provide improvements in the precision and hence the performance of positron emission tomography (PET) scanning and other medical detection systems. The patented technology was developed under a joint PET-MRI development alliance with the University of Washington.

“This patent is a direct result of Zecotek’s collaboration with the University of Washington one of the most prestigious medical imaging research teams in the world,” said Dr. Faouzi Zerrouk, Chairman, President and CEO of Zecotek Photonics. “The depth of interaction technology provides a fundamental new approach to the gathering and processing of data in medical imaging systems. We have filed additional patents on our new integrated detector module device which, by combining our patented scintillation crystals and solid-state MAPD photo detectors, provides the basic components required for a new generation of advanced PET-MRI scanning systems.”

The research team at the University of Washington is led by Professor Thomas Lewellen who is widely recognized as a leading researcher in the field. The joint PET-MRI development alliance utilizes Zecotek’s patented scintillation crystals and solid-state MAPD photo-detectors and expertise in optical components design, along with the University of Washington’s unique data acquisition methodologies and image reconstruction algorithms for new scanners.

The overall project is managed by Zecotek Photonics wholly owned subsidiary, Zecotek Imaging Systems (Singapore) Pte Ltd.

The exclusive rights to commercialization of this patent obtained under the license agreement with the University of Washington represent another important operational step toward Zecotek’s goal of developing and commercializing a proprietary PET/MRI system.
