Abstract
Methods of generating a gradient signal, gradient signal generators and magnetic resonance imaging systems are provided. In one aspect, a method includes obtaining a target amplitude and a target duration associated with a target precision corresponding to the gradient signal; generating a first actual amplitude by intercepting the target amplitude according to an actual precision of a DAC; generating a second actual amplitude according to the first actual amplitude, wherein a difference between the second actual amplitude and the first actual amplitude is 1; determining a first actual duration of outputting the first actual amplitude and a second actual duration of outputting the second actual amplitude according to the target amplitude, the target duration, the first actual amplitude and the second actual amplitude; controlling the DAC to output the first actual amplitude according to the first actual duration and output the second actual amplitude according to the second actual duration.
