Abstract
The present disclosure relates to systems and methods for medical imaging. The method may include obtain scanning data and at least one prior image of a subject. The method may include determining a restriction factor for each of the at least one prior image based on the scanning data. The restriction factor of the each prior image may relate to a motion of the subject corresponding to the scanning data. The method may include determining an objective function based on the restriction factor. The method may also include reconstructing, using the objective function, a target image of the subject based on the scanning data and the at least one prior image.
Claims20
A system, comprising:
- at least one storage device including a set of instructions;
- and
- at least one processor configured to communicate with the at least one storage device, wherein when executing the set of instructions, the at least one processor is configured to direct the system to perform operations including:
- obtaining scanning data and at least one prior image of a subject;
- determining a restriction factor for each prior image of the at least one prior image based on the scanning data, the restriction factor of the each prior image relating to a motion of the subject corresponding to the scanning data;
- determining an objective function based on the restriction factor;
- and
- reconstructing, using the objective function, a target image of the subject based on the scanning data and the at least one prior image, wherein the at least one prior image of the subject includes two or more prior images, the two or more prior images are reconstructed based on reference data corresponding to different reference scanning angle ranges, and the two or more prior images correspond to different restriction factors.
A method implemented on a computing device having a processor and a computer-readable storage device, the method comprising:
- obtaining scanning data and at least one prior image of a subject;
- determining a restriction factor for each prior image of the at least one prior image based on the scanning data, the restriction factor of the each prior image relating to a motion of the subject corresponding to the scanning data;
- determining an objective function based on the restriction factor;
- and
- reconstructing, using the objective function, a target image of the subject based on the scanning data and the at least one prior image, wherein the at least one prior image of the subject includes two or more prior images, the two or more prior images are reconstructed based on reference data corresponding to different reference scanning angle ranges, and the two or more prior images correspond to different restriction factors.
A non-transitory computer-readable storage medium including instructions that, when accessed by at least one processor of a method, cause the system to perform a method, the method comprising:
- obtaining scanning data and at least one prior image of a subject;
- determining a restriction factor for each prior image of the at least one prior image based on the scanning data, the restriction factor of the each prior image relating to a motion of the subject corresponding to the scanning data;
- determining an objective function based on the restriction factor;
- and
- reconstructing, using the objective function, a target image of the subject based on the scanning data and the at least one prior image, wherein the at least one prior image of the subject includes two or more prior images, the two or more prior images are reconstructed based on reference data corresponding to different reference scanning angle ranges, and the two or more prior images correspond to different restriction factors.
