SINGAPORE, June 16, 2015 /PRNewswire/ - Zecotek
Photonics Inc. (TSX-V: ZMS; Frankfurt: W1I;OTCPK: ZMSPF), a developer
of leading-edge photonics technologies for industrial, healthcare
and scientific markets, is pleased to announce that the Company's
patented LFS scintillation crystals achieved a more precise
coincident time resolution (CTR) when compared to competing
crystals in tests conducted by a CERN research group, on crystals
with dimensions used in commercial positron emission tomography
(PET) medical scanners. The results were presented at a
recent 2015 IEEE Nuclear Science Conference in Seattle and have been published in major
journals.i
"The results of the comparative timing measurements study,
clearly show that Zecotek's LFS scintillation crystals have more
precise coincidence time resolution," said Dr. Crispin Williams,
Senior Research Scientist at CERN. "The coincidence timing
resolution is key in time-of-flight PET medical scanners. It
improves the image signal to noise ratio and allow for shorter
scanning times. Our team is impressed with the test results and
with the competitive pricing of the LFS crystals. We are therefore
proceeding to use Zecotek's LFS crystals for our PET – CERN
projects."
"With such a low coincidence timing resolution, Zecotek's LFS
scintillation crystals present PET scanner OEMs the opportunity to
improve the performance of new generation time-of-flight scanners
targeting substantial markets," said Dr. A.
F. Zerrouk, Chairman, President, and CEO of Zecotek
Photonics Inc. "The advantages our LFS crystal: high density,
fast decay time, very good energy resolution and superior radiation
hardness when compared to competing crystals when used in PET
scanners and high energy particles experiments, have established
them as a leading choice. Other institutions including PET
OEMs are testing the LFS crystals and BOET, our manufacturing
partner is taking steps to increase its manufacturing capabilities
in order to prepare for recent and future demand."
The tests were conducted in the context of designing a
time-of-flight PET scanner. These newly developed scanning
devices are for the high resolution detection of lesions and
cellular defects. PET scanners need to detect the gamma photons
emanating from the patient's body as a result of an intravenous
injection of radio trace substance. Over the years, OEMs have
improved the configuration of PET scanners; the main differentiator
for superior performance lies with the crystal.
To achieve the speed necessary for quick, high resolution output
the scintillation crystals must be very dense, must have high
energy resolution and must possess a fast decay time. As the
PET industry moves toward producing time-of-flight PET scanners,
the use of crystals with these properties, is paramount.
Zecotek's patented LFS crystals are uniquely positioned because
they meet the three main properties required.
