An inexpensive MRI device that can image solid structures with short T2 times was developed by adding gradient coils, pulse sequences, and a GUI to a 0.34T commercial spectrometer. Gradient coils were created by hand winding or additive manufacturing. The 3D-printed coils produced a homogenous gradient and minimized acoustic noise. The GUI was created so that custom pulse sequences could be programmed, data gathered, and images reconstructed. Custom pulse sequences were encoded in C including: gradient echo pulse sequence; spin echo pulse sequences; and three dimensional volume acquisitions. Images were obtained under one second with 50 micron resolution.
