Claim 8:
9. The method of claim 7, wherein in response to determining that the intermediate subsampling model does not satisfy the termination condition, the updating the intermediate subsampling model based on the intermediate MRI reconstruction model and at least a portion of the first training samples comprises:
for each of the at least a portion of the first training samples,
generating, based on the predicted full MRI image of the training sample, predicted full k-space data;
obtaining, based on the full MRI data of the training sample, full k-space data; and
generating a comparison result between the predicted full k-space data and the full k-space data of the training sample; and

updating the intermediate subsampling model based on the comparison result of each of the at least a portion of the first training samples.
