Claim 5:
6. The data processing apparatus of claim 1, wherein the processing circuitry is configured to, in obtaining the generated complete sets of low-kV and high-kV projection data:
perform sinogram completion to the set of projection data to obtain processed low-kV projection data and processed high-kV projection data;
obtain 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;
apply 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
obtain 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.
