The designed yoke is not yet complete, but since the magnet is available, we attempted to acquire spin-echo signals.画像画像The system was wrapped in aluminum foil for noise reduction.画像Although a little noisy, we were able to obtain the NMR signal of water in a small bottle.

画像In addition, a miniature MRI gradient coil was designed using the target field method in MATLAB.

画像The contour lines are the wires of the coil.

画像Edit the contour lines calculated in MATLAB and convert them to data for the Kicad pattern, and you are done.画像画像Gradient coils are installed this way.
