1. A distributed data collection architecture for a positron emission tomography (PET) imaging system, comprising:
a plurality of data collection boards, wherein each data collection board of the plurality of data collection boards is coupled to a respective gantry segment of the PET imaging system, wherein the PET imaging system comprises a modular gantry having a plurality of gantry segments that are physically separate from each other, and each gantry segment of the plurality of gantry segments comprises a plurality of detector modules coupled to a respective data collection board of the plurality of data collection boards; and
wherein each respective data collection board of the plurality of data collection boards is configured to acquire all detector event data from a respective plurality of detector modules of the respective gantry segment the respective data collection board is coupled to, and only one data collection board of the plurality of data collection boards is configured to act as a master data collection board that collects all of the detector event data from each data collection board of the plurality of data collection boards and to generate coincidence pairs from all of the detector event data.
