Claim 3:
4. The method of claim 3, wherein the jointly training the preliminary subsampling model and the preliminary MRI reconstruction model includes an iterative operation including one or more iterations, and a target iteration of the one or more iterations includes:
obtaining, based on the preliminary subsampling model and the preliminary MRI reconstruction model, an intermediate subsampling model and an intermediate MRI reconstruction model;
determining whether the intermediate subsampling model satisfies a termination condition; and
in response to determining that the intermediate subsampling model does not satisfy the termination condition, updating, based on the intermediate MRI reconstruction model and at least a portion of the first training samples, the intermediate subsampling model.
