Patent ID: 8876377

Claim:
A sensor array for a medical imaging system, said sensor array comprising: a substrate configured to be mounted to a detector; a proximity sensor array including a plurality of sensors, at least some of the sensors disposed on a first side of the substrate, the substrate being deformable to correspond to a sensing surface of the detector, wherein the plurality of sensors include a plurality of transmitters and a plurality of receivers arranged in rows and columns, the plurality of receivers in each row being coupled together in electrical series, wherein a first portion of the transmitters receive an input from a first input line, a second portion of the transmitters receive an input from a second input line, the first portion of transmitters being interleaved with the second portion of transmitters, wherein a single transmitter and a single receiver form a cell, the system configured to iteratively read each cell in sequence to identify when an object is proximate to the sensor array; and a conductive sensor array including a first plurality of metallic pads disposed on a second side of the substrate, the second side opposite the first side, the metallic pads configured to cooperate with a second plurality of metallic pads to close at least one circuit to indicate contact between the substrate and an object to be imaged.
