Zecotek’s Proprietary MAPD Solid-State Photo Detectors Selected by the Paul Scherrer Institute, Switzerland
Vancouver, January 10 ,2008 – Zecotek Photonics Inc. (TSX-V: ZMS; Frankfurt: W1I) today announced that the Swiss-based Paul Scherrer Institute has selected Zecotek’s proprietary Micro-pixel Avalanche Photo Diodes (MAPD) for trials in its next-generation Positron Emission Tomography (PET) medical imaging program. The Paul Scherrer Institute PET program is focused on advancing improvements in sensitivity, spatial resolution and image quality in PET scanners, based on the understanding that advances in PET are driven largely by progress in instrumentation, in particular the performance of scintillation materials, photo-detectors and read-out electronics. Higher resolution PET scanners will provide more detailed diagnoses, result in improved patient outcomes and broaden PET applications in brain function analysis and diagnosis.
“The Paul Scherrer Institute is highly respected for its work in advancing medical imaging and we are delighted they have chosen both our MAPD photo detectors and, as previously announced, LFS scintillation crystal for their PET program,” said Dr. A.F. Zerrouk, Chairman, President, and CEO of Zecotek. “The MAPD photo detector and the LFS scintillation material form the core elements of a new class of detector array used in medical imaging. Our detector array offers improved performance at a lower cost and, because our MAPDs are not affected by magnetic fields, offers the potential break-through of an integrated PET-MRI (Magnetic Resonance Imaging) scanning device.”
Zecotek’s MAPD solid-state photo detectors have been designed in several configurations to offer significant performance and cost advantages over the current photo-multiplier vacuum tubes (PMT) and existing solid state photo-detectors. The MAPD-2 addresses specific, high-demand requirements in high-energy physics such as particle accelerators where PMT’s are vulnerable to the magnetic environment created by the superconducting magnets used in the collimation of particle tracks. The MAPD-3 meets required specifications for advanced, high resolution PET scanners and gamma camera applications, particularly when matched with Zecotek’s patented LFS scintillation materials. Photo detectors, together with the scintillation material, typically constitute 50 to 65% of the manufacturing cost of a PET scanner.
The selection of Zecotek’s MAPD photo detectors follows an extensive and competitive program of testing and evaluation. The MAPDs will be supplied through Zecotek Imaging Systems Pte. Ltd., Singapore, a wholly owned subsidiary of Zecotek Photonics Inc., and manufactured under contract by the Malaysian Institute of Microelectronic Systems.
