Abstract
The disclosure includes: judging whether a center line of an object to be scanned is deviated from a rotation axis of a gantry of a CT scanning device; determining a first distance by which the center line of the object to be scanned is deviated from the rotation axis in a case that the center line of the object to be scanned is deviated from the rotation axis; determining according to the first distance a second distance by which the shape filter is to be translated in each projection angle; and controlling the shape filter to make it translate by the second distance in each corresponding projection angle.
