Apparatus, methods, and other embodiments associated with magnetic resonance imaging (MRI) blipped trajectories having varying blip amplitudes are described. One example method includes controlling an MRI apparatus to produce a set of blipped trajectories including a first blipped trajectory having a first blip amplitude and a second, different blipped trajectory having a second, different blip amplitude. The blip amplitudes may be based on a relationship between a trajectory and a reference. The relationship may be, for example, a rotation angle. The rotation angle may be a proxy for information including a gradient trajectory speed associated with a blipped trajectory or an amount of unused gradient energy available while producing the blipped trajectory. The blip amplitudes may be selected to produce incoherent sampling during an MRI acquisition that uses the blipped trajectories. In one example, readout directions may be altered between trajectories to reduce regularity in k-space.
