Abstract
A circuit () for use in an magnetic resonance (MR) system to reduce MR interference of a physiological signal S(f) includes a first summing/subtraction node (), a high pass filter (), and a second summing/subtraction node (). The first summing/subtraction node () inputs a first signal () including radio frequency magnetic interference N(f) and a physiological signal S(f), and a second signal () including the physiological signal S(f) and an error signal E(f), and subtractively combines the second signal with the first signal to generate a difference signal N(f)−E(f). The high pass filter () filters the difference signal N(f)−E(f) from the first summing/subtraction node. The second summing/subtraction node () subtractively combines the first signal S(f)+N(f) () and the filtered signal H(f)*[N(f)−E(f)] from the high pass filter, and generates the second signal S(f)+E(f) ().
