Latest Patents

One of Arnott's latest patents is the Silicon photomultiplier based TOF-PET detector. This scintillation block detector employs an array of optically air coupled scintillation pixels, which are wrapped in reflector material. It is optically coupled to an array of silicon photomultiplier light sensors with common-cathode signal timing pickoff and individual anode signal position and energy determination. The design features an optimized combination of photopeak energy event sensitivity and timing, while reducing electronic circuit complexity and power requirements. Additionally, it eases necessary fabrication methods. Four of these small blocks, or 'miniblocks,' can be combined as optically and electrically separated quadrants of a larger single detector to recover detection efficiency that would otherwise be lost due to scattering between them. Events are validated for total energy by summing the contributions from the four quadrants. The trigger is generated from either the timing signal of the quadrant with the highest energy deposition, the first timing signal derived from the four quadrant time-pickoff signals, or a statistically optimum combination of the individual quadrant event times. This approach maintains good timing for scatter events and further reduces the number of electronic channels required per unit detector area while avoiding the timing degradation characteristic of excessively large SiPM arrays.
