1. A method implemented on at least one computing device each of which has at least one processor and storage, the method comprising:
acquiring first PET data at a time interval;
acquiring a plurality of correction coefficients, wherein the plurality of correction coefficients include a normalization coefficient corresponding to the first PET data, and a scale factor determined based at least in part on the normalization coefficient;
correcting the first PET data based on the plurality of correction coefficients; and
reconstructing an image based on the corrected first PET data.
