Abstract:
1. A computer-implemented method performed by a computer controlling a magnetic resonance imaging (MRI) apparatus and producing variable blipped trajectories during an MRI acquisition, comprising: the computer controlling the magnetic resonance imaging (MRI) apparatus in order to produce and apply a set of blipped trajectories, during an MRI acquisition where the set of blipped trajectories includes: and the computer controlling the MRI apparatus to associate a first readout direction with the first blipped trajectory and controlling the MRI apparatus in order to associate a second, different readout direction with the second blipped trajectory, where performing the MRI acquisition using the first readout direction for the first blipped trajectory and using the second readout direction for the second blipped trajectory produces less regularity in k-space than is produced by performing the MRI acquisition using the first readout direction as both the first blipped trajectory and the second blipped trajectory, and where performing the MRI acquisition using the first blip amplitude and the second blip amplitude produces an optimal incoherent sampling during the MRI acquisition.
