Magnetic susceptibility imaging method and system and storage medium

The embodiment of the invention provides a magnetic susceptibility imaging method and system and a storage medium. The method comprises the following steps: acquiring at least one group of echo data corresponding to at least one acquisition time period; sequentially transmitting each group of echo data to at least one target graphics processor, and controlling the at least one target graphics processor to combine the echo signals of the plurality of channels in each group of echo data based on the weight of each channel in the plurality of channels to obtain combined data corresponding to each group of echo data; determining at least one phase difference calculation group, sequentially transmitting two groups of echo data in each phase difference calculation group to at least one target graphics processor, and controlling the at least one target graphics processor to obtain a phase difference diagram corresponding to each phase difference calculation group; and acquiring at least one phase difference image an
