LYSO(Ce) array is a kind of crystal matrix which is the most popular array used in Positron Emission Tomography(PET) facility. 
LYSO(Ce) array is an essential component used in Positron Emission Tomography(PET) facility, included whole body, small animal and specific organ like brain, Breast, thyroid, etc. 
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, excellent energy resolution. These properties make LYSO an ideal candidate for a range of ray detection applications in nuclear physics and nuclear medicine, which require higher, improved timing resolution and superior energy revolution. 
LYSO (Lu 1.8Y.2SiO5:Ce) is a Cerium doped Lutetium based scintillation crystal that offers high density and short decay time.  It is ideal for applications that require higher throughput, better timing and energy resolution, including time-of-flight PET. PET applications have traditionally used arrays of BGO. LYSO crystal competes directly on density and surpasses BGO on energy resolution, timing and throughput.
