Conventional Extended Phase Graphs (EPGs) allow for an efficient analysis of signal behavior in MRI sequences involving spoiling gradients. The concept has been adapted to spatially resolved EPGs, where spoiling and spatial information is assumed to be fully uncoupled. In this work, we formulate an approach for the combination of configuration state theory and the conventional k-space concept, by re-coupling spoiling and spatial information. The concept not only permits investigating the interference of spoiled signals leading to additional ringing artifacts, but also allows to study arbitrary readout trajectories in the realm of EPGs.
