Abstract
Systems and methods for reducing signal noise in an x-ray emitter/detector system are disclosed. A common clock is connected to at least two subsystems of the x-ray emitter/detector system to enable a plurality of noise sources associated with the at least two subsystems within the x-ray emitter/detector system to be correlated with the common clock. At least one adaptive filter having a plurality of taps is configured to receive a desired signal and a correlated noise estimate signal and output an error signal. An update algorithm is used to update a value of the plurality of taps to minimize the error signal output to thereby substantially remove at least one of the plurality of noise sources at each of the at last one variable filters in the x-ray emitter/detector system to provide a more accurate display of the output of the x-ray emitter/detector system.
