METHOD AND APPARATUS FOR CONTROLLING SHAPE FILTER IN CT SCANNING DEVICE |
| 摘要 |
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. |

1. A method for controlling a shape filter in a CT scanning device, wherein the CT scanning device comprises a tube, the shape filter and a detector, the tube and the detector are able to rotate around a rotation axis of a gantry of the CT scanning device, and the shape filter is able to be translated relative to the tube, and wherein the method comprises:
judging whether a center line of an object to be scanned is deviated from the rotation axis; 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. |
