System and method for 3d image reconstruction from axial step-and-shoot ct

A method for image reconstruction implemented on at least one device including at least one processor and at least one storage, the method comprising:

• obtaining scanning data of a subject, wherein the scanning data is generated by at least one detector via a plurality of axial scans;
• determining a plurality of initial image locations associated with the plurality of axial scans;
• determining a plurality of intermediate image locations based on the plurality of initial image locations, wherein an amount of the plurality of intermediate image locations is larger than an amount of the plurality of initial image locations;
• determining a plurality of intermediate images based on the plurality of intermediate image locations and the scanning data;
• and
• determining a plurality of final images based on the plurality of intermediate images.

A non-transitory computer readable medium comprising executable instructions that, wherein when executed by at least one processor, the executable instructions cause the at least one processor to effectuate a method comprising:

• obtaining scanning data of a subject, wherein the scanning data is generated by at least one detector via a plurality of axial scans;
• determining a plurality of initial image locations associated with the plurality of axial scans;
• determining a plurality of intermediate image locations based on the plurality of initial image locations, wherein an amount of the plurality of intermediate image locations is larger than an amount of the plurality of initial image locations;
• determining a plurality of intermediate images based on the plurality of intermediate image locations and the scanning data;
• and
• determining a plurality of final images based on the plurality of intermediate images.
