摘要: An apparatus for active vibration is provided for control of resonance vibrations in a computed tomography (CT) system. The apparatus comprises a sensor coupled to a support frame of the CT system for detecting resonance vibrations and and convert the vibration signal to a corresponding electrical signal. The apparatus further comprises a control device coupled to the sensor for implementing a control algorithm to process the electrical signal to generate a corresponding control signal, which is used for counteracting the resonance vibrations in the support frame.
