Methods and systems for an imaging system including a detector and a data acquisition system are provided. The data acquisition system includes a plurality of terminations, at least one of the terminations coupled to a signal lead of a respective detector element, the circuit board connector positioned proximate the detector to facilitate reducing an input capacitance of the respective detector element signal leads, and at least one connector slot configured to receive a single analog to digital converter board (A/D board), the connector slot further configured to receive two A/D boards in a back-to-back configuration with respect to each other.
