The Extended Phase Graph (EPG) calculus can be understood as a solution of the Bloch equation using its k‑space representation. The ability to represent magnetization in phase state configurations frequently enables an intuitive and pictorial understanding of echo formation and assignment. A class of functions that allows for the easy calculation and simulation of EPGs for arbitrary MR sequences was developed (EPGspace) and its key points are presented. The EPGspace source code is made publically available for download in the internet.
