A system for acquisition of tomographic measurement data from measurement signals (S) of positron emission tomography (PET) or single-photon emission computed tomography (SPECT) detectors, the system comprising: a front-end electronic assembly () configured to convert the measurement signals (S) into digital and analog signals (DAS); a measurement electronics assembly () comprising time to digital converter (TDC) modules () configured to determine times (T) of pulses in digital signals (DS). The measurement electronics assembly () comprises: a series (TDCa-TDCd) of TDC modules (), each module comprising a series (TDC-TDC) of TDC circuits (-); a module controller () configured to transmit a clock signal (CLK), input to the module controller () from a system controller (), to each of the TDC circuits (-); wherein each of the TDC circuits (-) is configured to execute measurements in a measurement window delimited by the neighboring edges of the clock signal (CLK) which is common for all TDC circuits (-).
