Abstract: A computed tomography imaging system includes a gantry. The computed tomography imaging system further includes a rotating frame rotatably supported in the gantry. The rotating frame includes an X-ray source configured to emit X-ray radiation that traverses an examination region and an X-ray radiation sensitive detector disposed opposite the X-ray source across the examination region and configured to detect X-ray radiation traversing the examination region and generate a signal indicative of the detected X-ray radiation. The computed tomography imaging system further includes at least one component of the gantry or the rotating frame that produces audible noise. The computed tomography imaging system further includes an audible noise reducer configured to reduce the audible noise. The audible noise reducer includes a resonator tuned to a first frequency of the audible noise.
