A high critical temperature (Tc) superconducting bulk magnet is a promising magnet for magnetic resonance (MR) microimaging since it produces a strong (up to 17 T) and very stable (0.018 T/hour) magnetic field with a small installation space. However, the major application for the bulk magnet is now limited to MR microimaging of small objects because the room temperature bore diameter is limited. In such case, a long signal averaging time is required to achieve sufficient signal-to-noise ratio due to the small voxel volume.In this study, we demonstrated usefulness of compressed sensing in MR microimaging using the high Tc bulk magnet.
