A new open‐source software project is presented, JEMRIS, the Jülich Extensible MRI Simulator, which provides an MRI sequence development and simulation environment for the MRI community. The development was driven by the desire to achieve generality of simulated three‐dimensional MRI experiments reflecting modern MRI systems hardware. The accompanying computational burden is overcome by means of parallel computing. Many aspects are covered that have not hitherto been simultaneously investigated…

Concomitant gradient terms in phase contrast MR: Analysis and correction
This paper theoretically and experimentally shows the existence of two additional lowest‐order terms in the concomitant field, which it is called cross‐terms, which only arise when the longitudinal gradient Gz is simultaneously active with a transverse gradient (Gx or Gy).
