Systems and methods for focal point position correction |
abstract |
Systems and methods for determining an offset of a position of a focal point of an X-ray tube is provided. The methods may include obtaining at least one parameter (thermal capacity of anode) associated with an X-ray tube during a scan of a subject and obtaining a position of a focal point of the X-ray tube. The methods further includes determining a target offset of the position of the focal point based on the at least one parameter and a target relationship between a plurality of reference parameters associated with the X-ray tube and a plurality of reference offsets of reference positions of the focal point. The methods further includes causing, based on the target offset, a correction on the position of the focal point of the X-ray tube.It is also disclosed to recalculate the current anode thermal capacity (and thus the corresponding focal spot positional offset of the x-ray tube) in a manner similar to that of IEC Standard 60613 (cf. fig. 8). |
