Claim 15:
16. The data processing method of claim 11, wherein obtaining the generated complete sets of low-kV and high-kV projection data comprises:
performing sinogram completion to the set of projection data to obtain processed low-kV projection data and processed high-kV projection data;
obtaining a first low frequency component of the processed low-kV projection data and a second low frequency component of the processed high-kV projection data;
applying a first neural network to the first low frequency component to obtain a first processed low frequency component, and apply a second neural network to the second low frequency component to obtain a second processed low frequency component; and
obtaining the generated complete set of low-kV projection data and the generated complete set of high-kV projection data, based on the first processed low frequency component and the second processed low frequency component.
