Active damping for open MRI image stabilization

摘要

A control instrumentation system is provided for active vibration reduction in an open MRI system. The control instrumentation system comprises a sensor coupled to a post of the open MRI system for detecting vibration signals and converting the vibration signal to a corresponding electrical signal, a digital signal processor implementing a control algorithm to process the electrical signal to generate a corresponding control signal and an actuator receiving the control signal and using the control signal to minimize the vibration of the system.
