[0002] Magnetic resonance imaging technology has become one of the important tools for clinical diagnosis and research in medicine. It has the characteristics of being non-invasive, non-ionizing, and radiation-free. The radio frequency coil is an important component of the imaging system, which plays a vital role in the imaging quality and directly affects the image signal-to-noise ratio.

[0003] The center of the birdcage coil can generate a relatively uniform radio frequency electromagnetic field, so the magnetic resonance system usually uses a birdcage coil as a transmitting coil or a common transmitting and receiving coil. The structure of a traditional birdcage coil is usually a unified whole. When a problem occurs with a local coil, the entire birdcage coil needs to be dismantled for inspection or replacement, which is cumbersome and inconvenient, and is not conducive to the simple assembly and flexible use of the birdcage coil. Therefore, it still needs to be improved. Utility Model Content

[0016] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0017] Any feature of this specification, unless otherwise specified, can be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise specified, each feature is only an example of a series of equivalent or similar features.

[0018] like Figure 1 , 2The double-tuned head birdcage coil shown is easy to disassemble and assemble, comprising a disassembly plate 3, an insertion ring 1 and a fixed plate 2. The disassembly plate 3 is provided with a plurality of disassembly plates 3 and the structures of the plurality of disassembly plates 3 are the same. Insertion strips 5 are provided at the front and rear ends of the disassembly plate 3. The interior of the disassembly plate 3 is a hollow structure. An imaging coil is installed inside the disassembly plate 3. A snap-fit ​​buckle 4 is provided at the left end of the disassembly plate 3, and a snap joint 6 is provided at the right end of the disassembly plate 3. A plurality of disassembly plates 3 are snap-fitted with the snap joint 6 through the snap-fit ​​buckle 4 to be assembled and connected to form a circular ring structure. The insertion ring 1 is installed at the front end of the disassembly plate 3, and the fixed plate 2 is installed at the rear end of the disassembly plate 3.

[0019] like Figure 3 As shown, the card connector 6 includes a card plate 7 and a card strip 9, the card plate 7 is provided with a through hole 8 near the front end, the end of the card strip 9 is provided with a rotating shaft 10 and is connected to the card plate 7 through the rotating shaft 10, a connecting groove 11 is provided on the card strip 9, a U-shaped groove 12 is provided near the front end of the card strip 9, a paddle 14 is provided at the front end of the card strip 9, and the paddle 14 is integrally formed with the card strip 9.

[0020] A limiting block 13 is disposed on the U-shaped groove 12 .

[0021] like Figure 4 , 5 As shown, the insertion ring 1 and the fixing plate 2 are both provided with a plurality of insertion openings 15 , and rubber pads 16 are provided on the inner wall surfaces on the left and right sides of the insertion openings 15 .

[0022] During use, the snap buckle 4 on the left side of one disassembly plate 3 is placed in the snap joint 5 on the right side of the other disassembly plate 3, that is, the card strip 9 is rotated upwards through the shaft 10 to open the snap joint 5, and then the snap buckle 4 is placed in the connecting groove 11. After the snap buckle 4 is placed, the shaft 10 is rotated downwards to make the card strip 9 gradually approach the card board 7. When the card strip 9 reaches the card board 7, the paddle 14 is squeezed to the left to reduce the diameter of the U-shaped groove 12, so that the U-shaped groove 12 can smoothly pass through the through hole of the card board 7. Hole 8, after the U-shaped groove 12 passes through the through hole 8, release the pressure on the paddle 14, at this time, the diameter of the U-shaped groove 12 returns to the original diameter and the limit block 13 on the U-shaped groove 12 will be stuck at the bottom of the card plate 7, thereby completing the assembly and connection of the two disassembly and assembly plates 3, after multiple disassembly and assembly plates 3 are assembled into a circular ring structure, the plug-in strips 5 at the front and rear ends of the disassembly and assembly plates 3 are respectively matched with the plug-in ring 1 and the plug-in openings 15 on the fixed plate 2 one by one and inserted, thereby completing the installation of the entire head birdcage coil.

[0023] The provision of the rubber pad 16 can increase the friction between the insertion opening 15 and the insertion strip 5 , thereby making the insertion strip 5 more firmly fixed.

[0024] The beneficial effects of the utility model are as follows: the utility model has a reasonable structural design and is easy to use. It can simply and quickly assemble multiple disassembly plates, fixed plates and plug-in rings into a complete head birdcage coil. It can also facilitate local coil replacement, thereby improving the disassembly and assembly convenience and use flexibility of the head birdcage coil.

[0025] The present invention is not limited to the above-mentioned specific implementation modes, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
