Patent ID: 7436494

Claim:
An electronic circuit comprised of: photon detector array means for converting photons to a detector output signal, a plurality of readout electronics integrated circuit chips, each readout electronics integrated circuit chip comprising a plurality of channels for receiving and processing output signals generated by said photon detector array, wherein said plurality of readout electronics integrated circuit chips are arranged in a stacked configuration with each of said readout electronics integrated circuit chips forming one layer of said stacked configuration, wherein said photon detector array is bonded to a lateral surface of said stacked configuration perpendicular to said stacked configuration and connected to the plurality of channels via a plurality of T-connects disposed on said lateral surface of said stacked configuration, wherein at least two of said channels comprise, converting circuit means for converting said detector output signal to a digitized data value comprised of one or more digital bits comprising an image data set wherein each digital bit has a position in said image data set, reference insert circuit means for inserting one or more user-defined reference points at one or more predetermined positions in said image data set, and, reference point synchronization circuit means for synchronizing at least one of said user-defined reference points with at least one other of said user-defined reference points in each of at least two of said channels' image data sets.
