The full patten is arranged as 3x3 matrix of dots. Each part has different brightness and centering dot:
Update: The open access Sensors journal published the Stanford University paper titled "Photo-Detectors for Time of Flight Positron Emission Tomography (ToF-PET)". The paper reviews recent advances in time of flight positron emission tomography (ToF-PET) based on two types of photo-detectors: photomultiplier tubes (PMTs) and silicon photo-multipliers (SiPMs) with a special focus on SiPMs.
