Abstract
Systems, methods and apparatus are provided through which in some embodiments the line time of an X-Ray detector is dynamically selected so as to nullify an aliased interference signal. The frequency of a noise signal generated by a source external to the digital X-ray detector is determined and, based on the determined frequency, the line time of the digital X-ray is adjusted so as to compensate for the interfering noise. The frequency of the noise can be directly determined from an electromagnetic interference (EMI) sensor or derived through analysis of the power spectrum of the noise signal.
