In a method, apparatus and storage medium for filling a k-space trajectory in magnetic resonance (MR) imaging, a blank window, following an RF excitation pulse, is set in an arbitrary spatial encoding direction, and a first MR signal is acquired in this blank window, to obtain the phase of the first MR signal. A gradient field is activated outside the blank window and a second MR signal is acquired to obtain the phase of the second MR signal. This first and second MR signals are entered into k-space along first k-space and second k-space trajectories that are respectively based on the phase of the first MR signal and the phase of the second MR signal. A calibrated k-space trajectory in the spatial encoding direction is determined based on the first and second k-space trajectories.
