Magnetic-resonance imaging method, apparatus and system, and storage medium

A magnetic-resonance imaging apparatus, comprising at least one processor and a memory for storing a computer program that when executed by the processor causes the processor to perform steps in following modules:

• an initial-imaging-model establishing module, which is configured to acquire an original model for magnetic-resonance imaging and establish an initial imaging model according to an iterative algorithm used for solving the original model, wherein the iterative algorithm comprises at least one of an undetermined parameter, an undetermined solving operator or an undetermined structural relationship;
• a model-training module, which is configured to train the initial imaging model on a basis of sample data to generate a magnetic-resonance imaging model, wherein training of the initial imaging model is used for learning the at least one of the undetermined parameter, the undetermined solving operator or the undetermined structural relationship in the iterative algorithm;
• and
• a magnetic-resonance imaging module, which is configured to acquire under-sampled K-space data to be processed, input the under-sampled K-space data into the magnetic-resonance imaging model, and generate a magnetic-resonance image.
