Claim 17:
18. The system of claim 17, wherein the training the second model includes a second iterative operation including one or more iterations, each of at least one iteration of the second iterative operation including:
for each of at least some of the plurality of training samples, generating an output image of the second model by inputting the sample concatenated image of the training sample and the corresponding preliminary image into an updated second model determined in a previous iteration;
determining, based on the output image of the updated second model and the sample attenuation-corrected PET image corresponding to each of the at least some of the plurality of training samples, a second assessment result; and
further updating the parameter values of the updated second model to be used in a next iteration based on the second assessment result.
