Description
Good energy and timing resolutions are key parameters for new generations of PET detectors. In particular, the implementation of detectors with minimum electronics, potentially only passive components, is desired. This will improve the cost but more importantly the power consumption of the final scanner, which will further reduce requirements for cooling and
space.
In this work, we benchmark four circuit configurations with low power consumption. The tests were carried out using 3x3x5 mm3 LYSO:Ce:Ca crystals and FBK NUV SiPM. The two best scenarios provide a combination of 7% energy resolution and 96.7 ps CTR for 300 mW power consumption per detector, with two
channels; and 115.1 ps and 12% energy resolution for a circuit without active components and a virtual zero power consumption, with one channel. We will further develop these solutions into system-level arrays with deployment potential.
