摘要： A receiving device for an MRI (magnetic resonance imaging) system has multiple receiving coils. In the same imaging acceleration direction, a junction region is formed between adjacent receiving coils. An additional receiving coil is arranged on the junction region. The additional receiving coil covers at least partially a line of strong phase variation in sensitivity at the boundary of said junction region. This receiving device alleviates the problem of poor sensitivity to MRI signals in the junction region in the imaging acceleration direction, so as to improve the imaging quality in the junction region, and thus improving the overall imaging quality.

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.
摘要翻译：用于磁共振成像的腕线圈具有由连续拼接在一起的多个线圈拼接单元形成的管状线圈和缠绕在管状线圈的表面上的环形线圈单元。由于环形线圈单元缠绕在管状线圈的表面上，并且环形线圈单元中的电流方向与每个线圈接合单元中的电流方向垂直，所以当管状线圈中的一些线圈接合单元由于它们的磁场方向与主磁场方向的磁场方向平行，所以不能获取信号，所以环形线圈单元将执行信号采集。此外，由于环形线圈单元的磁通量相对较大，因此无论采用何种布局位置，腕部线圈都可以获得相对较高的信噪比，从而降低了设备成本并消除了对现有技术中的临床应用。

摘要： An identification code circuit for a receiving coil in a magnetic resonance imaging system, is embodied in a main coil. The circuit has a fixed resistance for generating the identification code of the main coil. The main coil has a socket for connecting a sub-coil, so that a coil plug of a sub-coil can be plugged into the socket for connecting to the main coil. The identification code circuit also has a regulating resistance and a sub-coil switch corresponding to the socket. The coil plug of the sub-coil is plugged into the socket to close the sub-coil switch, so that the values of the regulating resistance and said fixed resistance are added together to form a combined resistance value. After said main coil has been connected to a magnetic resonance imaging system, an identification code source voltage value across the combined resistance value is the identification code of the combined main coil and sub-coil. A receiving circuit identification code thus can be generated simply and with reduced cost.

The transmission circuit also has a first switch unit and a second switch unit. The first switch unit is connected to the first radio frequency output port and outputs the radio frequency signals which are emitted from the first radio frequency output port or reflects the radio frequency signals which are emitted from the first radio frequency output port back to the first radio frequency output port. The second switch unit is connected to the second radio frequency output port and outputs the radio frequency signals which are emitted from the second radio frequency output port, or reflects the radio frequency signals which are emitted from the second radio frequency output port back to the second radio frequency output port. The radio frequency signals reflected to the radio frequency input port by the first switch unit and the radio frequency signals reflected to said radio frequency input port by the second switch unit cancel each other. The transmission circuit has reduced complexity and cost.

摘要： A radio frequency (RF) switch device has at least two RF switch units, each RF switch unit having an output terminal and at least two input terminals. The RF switch units select one channel of RF signals from several channels of the RF signals that are supplied as inputs to their input terminals for emission as an output from their output terminals. A magnetic resonance imaging system and an RF signal transmission method employ such an RF switch device. The use of such an RF switch device reduces the number of channels of the RF signals that need to be further transmitted, which in turn reduces the number of the corresponding long RF cable channels and the number of channels of the subsequent devices, thereby preventing waste and reducing the cost of the system. Moreover, if the subsequent devices include a receiver coil channel selector, then the complexity of the receiver coil channel selector will also be reduced as the number of RF signal channels is decreased.
