A low-cost, open-interface classroom MRI scanner is demonstrated. The scanner was used in an undergraduate lab course to interactively teach the concepts of free induction decay, flip angle measurement, B0 shimming, gradient echo, spin echo, 1D projection, and 2D as well as 3D MR imaging. An open library of GUIs, pulse sequences, and reconstruction codes is being developed in MATLAB to help build a user base.
