Abstract
A method and a device for balancing a CT gantry device are provided. The method includes: obtaining a fluctuation chain of pulses generated in one revolution of the CT gantry and obtained when the CT gantry collects data; obtaining an eccentric angle of a center of mass according to the fluctuation chain, and calculating a magnitude of imbalance; and adjusting weight at a weight counterbalancing position according to the eccentric angle and the magnitude of imbalance, to locate the center of mass at the rotation center. The device includes a data collection unit for collecting a fluctuation chain, and a processor for obtaining an eccentric angle of a center of mass, and calculating a magnitude of imbalance; and the processor adjusts weight at the weight counterbalancing position according to the eccentric angle and the magnitude of imbalance, to locate the center of mass at the rotation center.
