摘要： The present invention relates to an oblique-driven platform structure, comprising: a base, a first rail, a screw, a first sliding block, a second sliding block, an oblique slide rod, at least one second rail, at least one third sliding block, a work platform, and a motor. There is a trigonometric relation between the oblique slide rod, the screw and the second rail, and an oblique drive angle is formed between the oblique slide rod and the screw; Therefore, with the change of the stroke position of the screw, the displacement resolution of the work platform can still kept the same value when the work platform is driven. Moreover, the displacement of the screw stroke can be proportionally transformed to the feed rate of the work platform through the trigonometric relation, such that the driven work platform can get an extremely high displacement resolution without using any high-level servo motor.

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.

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。
