1. A method for programming a scan sequence in k-space on a medical imaging system, the method comprising the following steps: providing a user interface including a graphic view of k-space for a medical imaging scan, the graphic illustration including a plurality of case based trajectories in the k-space; and displaying at least one sequence description component associated with the k-space through the user interface, the sequence description component defining a parameter for traversing k-space; and assigning a predefined order parameter to the sequence description component, the predefined order parameters associating conditional data with the downloadable sequence description component for sequencing the traversal of k-space.
