Cerium doped Lutetium Yttrium Silicate scintillation crystal (LYSO(Ce) scintillator) is an ideal generation scintillator crystal. LYSO scintillator has the advantages of high light output and density, quick decay time, and excellent energy resolution. These properties make LYSO an ideal candidate for various ray detection applications in nuclear physics and medicine, requiring higher, improved timing resolution and superior energy revolution. It is suitable for applications that require high throughput, good timing, and energy resolution, such as time-of-flight Positron Emission Tomography (PET). PET applications have traditionally used arrays of BGO. But LYSO crystal thoroughly beat BGO on density, energy resolution, and timing.
Hangzhou Shalom EO offers LYSO(Ce) pixelated scintillators and crystal arrays featuring high geometric precision and homogeneous light output, which makes the LYSO scintillation arrays one of the most popular scintillators used for PET usages, including PET for human diagnosis, animal diagnosis, and specific organs like brain, breast. We are capable of offering large LYSO(Ce) pixellated arrays with a pixel size as small as 0.3x0.3mm, which contributes to superior imaging resolution. Furthermore, for PET equipment requiring higher resolutions, single layers of scintillation arrays could be stacked into multilayer scintillation arrays to enhance the resolution. For this purpose, Shalom EO also offers Multilayer LYSO(Ce) Scintillation Arrays. If you are looking for Bulk LYSO(Ce) Crystals, click on the link to switch to our site's catalog.
