Nuclear medicine firm Zecotek Photonics said that the newest version of its lutetium fine silicate (LFS) scintillation crystals has achieved strong results in testing.
In testing by the University of Washington and by researchers affiliated with the European Organization for Nuclear Research (CERN), Zecotek's LFS-8 crystals had decay constants ranging between 15 and 25 nanoseconds depending on chemical compositions, with energy resolutions between 7% and 9%, according to Zecotek. The company said that existing lutetium oxide crystals have structural decay times of no less than 40 nanoseconds.
The LFS crystal properties are important to OEMs developing time-of-flight PET scanners for high-accuracy imaging, the firm said. Zecotek's LFS crystals are also characterized by high radiation hardness, making the LFS a good candidate for high-energy physics experiments.
