Systems and methods for magnetic resonance imaging

A system for magnetic resonance imaging (MRI), comprising:

• at least one storage device including a set of instructions;
• and
• at least one processor configured to communicate with the at least one storage device, wherein when executing the set of instructions, the at least one processor is configured to direct the system to perform operations including
• determining, based on first MRI signals collected in a first imaging stage of an MRI scan of a subject, an initial spatial factor;
• obtaining second MRI signals collected during a second imaging stage of the MRI scan after the first imaging stage;
• determining temporal factors or/and updated spatial factors, each of the temporal factors being determined based on the second MRI signals collected before the determination of the temporal factor, each of the updated spatial factors being determined based on the second MRI signals collected before the determination of the updated spatial factor;
• and
• generating real-time MRI images within the second imaging stage and transmitting the real-time MRI images to a terminal device for display, and each of the real-time MRI images being generated based on the latest determined temporal factor and one of the initial spatial factor or the latest determined spatial factor.

A method for magnetic resonance imaging (MRI), the method being implemented on a computing device having at least one storage device and at least one processor, the method comprising:

• determining, based on first MRI signals collected in a first imaging stage of an MRI scan of a subject, an initial spatial factor U0;
• obtaining second MRI signals {M1, M2, . . . , Mn}, Mi being collect at time Ti among time series {T1, T2, . . . , Tn} during a second imaging stage of the MRI scan after the first imaging stage;
• determining temporal factors {φ1, φ2, . . . , φn} and spatial factors {U1, U2, . . . , Um}, m being smaller than or equal to n, φi being determined based on the second MRI signals Mi, Uj being determined based on the second MRI signals {M1, M2, . . . , Mt}, 1<t<m and Mt being the latest second MRI signals obtained before the determination of Uj;
• and
• generating real-time MRI images {A1, A2, . . . , An} and transmitting the real-time MRI images to a terminal device for display, Ai reflecting the status of the subject at the time Ti, and being generated based on the temporal factor φi and one of the initial spatial factor U0 or the latest spatial factor determined before the time Ti.
