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 associated with an X-ray tube during a scan of a subject. The methods may further include determining a target offset of a position of a 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 may further include causing, based on the target offset, a correction on the position of the focal point of the X-ray tube.
Claims20
A method implemented on a computing device having at least one processor and at least one non-transitory storage medium, the method comprising:
- obtaining at least one parameter associated with an X-ray tube during a scan of a subject;
- determining a target offset of a position of a focal point of the X-ray tube 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 of the X-ray tube;
- and
- causing, based on the target offset of the position of the focal point of the X-ray tube, a correction on the position of the focal point of the X-ray tube.
A system, comprising:
- at least one non-transitory storage medium including a set of instructions;
- and
- at least one processor in a communication with the at least one non-transitory storage medium, wherein when executing the set of instructions, the at least one processor is configured to perform operations including:
- obtaining at least one parameter associated with an X-ray tube during a scan of a subject;
- determining a target offset of a position of a focal point of the X-ray tube 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 of the X-ray tube;
- and
- causing, based on the target offset of the position of the focal point of the X-ray tube, a correction on the position of the focal point of the X-ray tube.
A non-transitory_computer-readable medium, comprising at least one set of instructions, wherein when executed by at least one processor of a computing device, the at least one set of instructions direct the at least one processor to perform operations including:
- obtaining at least one parameter associated with an X-ray tube during a scan of a subject;
- determining a target offset of a position of a focal point of the X-ray tube 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 of the X-ray tube;
- and
- causing, based on the target offset of the position of the focal point of the X-ray tube, a correction on the position of the focal point of the X-ray tube.
