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.
