Abstract:
A wrist coil for magnetic resonance imaging has a tubular coil formed by a number of coil splicing units spliced together in succession, and an annular coil unit that is wound around the surface of the tubular coil. Since the annular coil unit is wound around the surface of the tubular coil, and the current direction in the annular coil unit is perpendicular to the current direction in each of the coil splicing units, when some of the coil splicing units in the tubular coil do not acquire signals due to the fact that their magnetic field direction is parallel to that of the main magnetic field direction, the annular coil unit will carry out signal acquisition. Furthermore, since the magnetic flux of the annular coil unit is relatively large, this ensures a relatively high signal-to-noise ratio in the acquired signals no matter whatever layout position is adopted for the wrist coil, thus reducing equipment costs and eliminating restrictions for clinical applications in the prior art.
