Instruction distribution method and device for magnetic resonance imaging sequence

The embodiment of the invention discloses an instruction distribution method and device for a magnetic resonance imaging sequence. The method comprises the steps that inter-block segmentation lines vertically penetrating through multiple time axes of a magnetic resonance imaging sequence are set, the magnetic resonance imaging sequence is segmented into multiple event blocks based on the inter-block segmentation lines, and each event block comprises pulse signals on the multiple time axes; according to the shape of the pulse combination in each event block, an in-block segmentation line vertically penetrating through a plurality of time axes is set in each event block, each event block is segmented into a plurality of sub-event blocks based on the in-block segmentation line, and each sub-event block comprises a single pulse type; a sub-event block is called from the plurality of sub-event blocks, and the called sub-event block is translated into a hardware instruction based on the pulse type contained in the
