We describe the design and application of an integrated MR console / MR physics simulation system. The system consists of a research MR console, a full-function hardware-independent pulse programming environment (over 40 sequences implemented); and a 44 CPU parallel Linux cluster for full Bloch equation simulations with stochastic spin modeling. The system allows precise side-by-side comparisons of experimental vs. simulated data for any real (not simplified) pulse sequence, and has numerous applications in MR research and development. The console has been installed on a 9.4T MRI. Real and simulated data are shown for a SSFP sequence.
