System and method for stabilization of an imaging positioner using an active mass damper

A method for operating an active mass damper system, comprising:

• receiving motion data from one or more motion sensors located in a C-arm, wherein the motion data is representative of motion of the C-arm;
• processing the motion data by applying one or more filters to the motion data to create filtered motion data;
• and
• controlling a linear motor, based on the filtered motion data and motor control tuning parameters, to move a mass in a linear reciprocating path to provide a force having a magnitude and a phase configured to dampen at least a portion of the motion of the C-arm.

An imaging device comprising:

• a C-arm supported by an attachment arm, wherein the c-arm comprises an imaging device and one or more sensors attached thereto configured to detect motion of the C-arm and output corresponding motion data representative of the motion of the C-arm;
• a mass damper assembly comprising a linear motor and a mass coupled to the linear motor, wherein the mass damper assembly is located within a portion of the C-arm;
• and
• a controller configured to:
• receive the motion data;
• process the motion data by applying one or more filters to the motion data to create filtered motion data;
• and
• control the linear motor, based on the filtered motion data and motor control tuning parameters, to move the mass in a linear reciprocating path to provide a force having a magnitude and a phase configured to dampen at least a portion of the motion of the C-arm.
