摘要： 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.

摘要： An examination bed for use in a magnetic resonance imaging system, has a bed board, a bottom antenna for an RF coil and a main body antenna for an RF coil. The bottom antenna is integrated in the inside or surface of the bed board, and forms a loop with the main body antenna, to form an RF coil. The thickness of the base plate is thereby reduced by integrating the bottom antenna into the bed board, thus increasing the available space to make the most of the limited space of the magnetic field for examination so that the examination bed can be used for those patients or other tested objects that would otherwise be oversized for the bed.

摘要： A mobile positioning device for an MRI inductively coupled coil, has at least one pair of coupled coils which are coupled with each other for transmitting signals, wherein one of the at least one pair of coupled coils is deployed on a surface of a patient's bed. A moveable platform is provided that can move in a direction parallel to the patient's bed, and the other one of the at least one pair of coupled coils is deployed on the moveable platform opposite to the coupled coil deployed on the patient's bed. The device can be driven by a motor or a spring. When the patient's bed needs to be placed at different positions for an examination, the coupled coil deployed on the moveable platform can be aligned completely and in parallel to the coupled coil fixed on the patient's bed by moving the moveable platform, so as to achieve the best coupling effects.

摘要： A volume coil for a magnetic resonance imaging system is composed of a number of coil units. In the coil, there are overlapped parts between two adjacent ones of the coil units for eliminating coupling between these two adjacent coil units. Two next-adjacent ones of the coil units, which are separated from each other by one coil unit, are each provided with an inductor, and these two inductors are coupled with each other for eliminating coupling between these two next-adjacent coil units. All coil units are collected on one axial end face of the coil. Two coil units in the coil that are neither adjacent coil units nor next-adjacent coil units are connected with each other on the end face by a capacitance circuit or a inductance circuit for eliminating the coupling between these two coil units that are neither adjacent coil units nor next-adjacent coil units. The coupling among the various coil units is relatively thoroughly eliminated, and the signal-to-noise ratio of the signal received by the coil is increased.
