Claim 11:
12. A method for controlling a magnetic resonance imaging (MRI) system, the method comprising:
performing a multi-pass, multi-echo or multi-repetition gradient echo pulse sequence that includes a phase increment of an RF pulse of the multi-pass, multi-echo or multi-repetition gradient echo pulse sequence selected to encode diffusion information into a phase of MR signals, wherein the RF pulse is performed at a beginning and an end of each pass, multi-echo or repetition and the phase increment is varied between passes or repetitions of the multi-pass, multi-echo or multi-repetition gradient echo pulse;
controlling the plurality of gradient coils and the RF system to acquire the MR signals as MR data;
processing the MR data to determine MR signals corresponding to diffusion in the subject when acquiring the MR signals; and
generating at least one of an image or a map of the subject indicating the diffusion in the subject from the MR data.
