Example Embodiment

[0019] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0020] Such as figure 1 As shown, the device of the present invention includes an upper cover plate 1, a lower cover plate 2, a center column 3, a spring 4, a pressure pin 5, a fixing clamp 6, a screw 9, and a ring 10. The upper cover 1 and the lower cover 2 are both in the shape of a flat racetrack. The upper cover 1 and the lower cover 2 are connected together by the center 3 pillars. The upper cover 1 and the lower cover 2 are provided with rectangular teeth on their periphery. A gap equal to the diameter of the superconducting wire is left between the rectangular teeth of the plate 1 and the lower cover plate 2. The superconducting wire 8 has a relatively large elastic force when it is bent, and if it is not bound, the arrangement of the superconducting wires is not tight. The ring 10 is sleeved on the central column 3, the ring 10 can rotate around the c...

Abstract

The invention relates to a winding device for a shimming superconducting coil, which comprises an upper cover plate (1), a lower cover plate (2), a central column (3), a spring (4), a pressure needle (5), a fixing clamp (6), a superconducting wire (8), a screw (9) and a ring (10). The upper cover plate (1) and the lower cover plate (2) are connected through the central column (3), and a clearancewith the size identical to the diameter of the wire is left between rectangular teeth of the upper cover plate (1) and the lower cover plate (2). The superconducting wire (8) pressed by the top end of the pressure needle (5) with the spring mechanism (4) slides along the circumference on a horizontal plane to be wound the superconducting coil.

Description

technical field [0001] The invention relates to a winding device and method of a superconducting coil, in particular to a winding device and a winding method of a superconducting coil for compensating the uniformity of a magnetic field. Background technique [0002] Compared with traditional medical imaging equipment such as X-rays, CT scanners, and ultrasonic imagers, MRI (Magnetic Resonance Imaging, MRI) systems have many imaging parameters, rich diagnostic information, high image resolution, and can be sliced ​​in any direction and wirelessly. With the advantages of ionizing radiation and other advantages, it has become the most advanced medical imaging equipment at present. The magnet is the core component used to provide the background magnetic field of the MRI system. The magnetic field strength is one of the important indicators of the MRI system, and it is directly proportional to the image signal-to-noise ratio. An MRI system with a high magnetic field strength can...
