Abstract
A CT system is provided that includes an outer housing, a rotatable gantry positioned within the outer housing and having a gantry opening to receive an object to be scanned, an x-ray source mounted on the rotatable gantry and configured to project an x-ray beam toward the object, and a detector array mounted on the rotatable gantry and configured to detect x-ray energy passing through the object and generate a detector output responsive thereto that can be reconstructed into an image of the object. A hybrid noise mitigation system is included in the CT system that is configured to mitigate noise generated by the CT system during operation, the hybrid noise mitigation system comprising a passive noise mitigation device configured to control noise in a passive manner and an active noise mitigation device configured to control noise in an active manner.
