Query: Investigation of the Power Consumption of the PETsys TOFPET2 ASIC   In state-of-the-art positron emission (PET) tomography systems,
application-specific integrated circuits (ASICs)are commonly used to precisely
digitize the signals of analog silicon photo-multipliers (SiPMs). However, when
operating PET electronics in a magnetic resonance (MR) system, one faces the
challenge of mutual interference of these imaging techniques. To prevent signal
deterioration along long analog signal lines, PET electronics with a low power
consumption digitizing the signals close to the SiPMs are preferred. In this
study, we evaluate the power consumption of the TOFPET2 ASIC. Its power
consumption ranges from 3.6 to 7.2 mW/channel as a function of the input stage
impedance and discriminator noise settings. We present an analytical model
allowing to compute the power consumption of a given ASIC configuration. The
configured input stage impedance and discriminator noise have an impact on the
coincidence resolution time, energy resolution, and photon trigger level. Since
the TOFPET2 ASIC delivers state-of-the-art performance with a power consumption
similar or even lower than other ASICs typically used for PET applications, it
is a favorable candidate to digitize the signals of SiPMs in future
simultaneous PET/MR systems.
