Abstract
Description
Technical Field
[0001] This utility model relates to the field of magnetic resonance imaging auxiliary equipment technology, specifically to a magnetic resonance shimming auxiliary device. Background Technology
[0002] Magnetic resonance shims, also known as magnetic resonance uniform fields, refer to the uniform magnetic field generated during magnetic resonance imaging (MRI). The generation of magnetic resonance shims is based on superconducting magnet technology. Superconducting magnets utilize the special properties of superconducting materials to form superconducting current loops at low temperatures, thereby generating a stable and uniform magnetic field. It is an important component of MRI equipment and plays a crucial role.
[0003] Magnetic resonance shimming plays two important roles in MRI: First, it creates a stable magnetic field environment: MRI requires a stable and uniform magnetic field environment to ensure the accuracy and precision of the imaging. Magnetic resonance shimming eliminates the influence of non-uniformity by generating a uniform magnetic field, providing a stable imaging basis. Second, it maintains the repeatability of imaging: MRI scans often need to be repeated multiple times to obtain more accurate results. The role of magnetic resonance shimming is to maintain the consistency of magnetic field strength and uniformity in each scan, thereby ensuring the repeatability of imaging, which is very important for medical diagnosis and scientific research.
[0004] During the sizing process, it is difficult for workers to compact the sizing iron sheets and plastic fillers when placing them into the sizing grooves of the sizing strip, which can easily lead to uneven stress. The sizing iron sheets in the sizing grooves may move, resulting in poor sizing effect. Furthermore, the method of placing the sizing iron sheets and plastic fillers is usually to compact them by hand, which is labor-intensive and inefficient.
[0005] Therefore, developing a magnetic resonance shimming auxiliary device that can conveniently and quickly compact all the filler in the shimming groove without causing the shimming iron sheet in the shimming groove to move is an urgent problem to be solved at this stage. Utility Model Content
[0006] To address the problems existing in the prior art, this utility model provides a magnetic resonance shimming auxiliary device. Several pressure blocks are distributed on the lower surface of the frame and match the shape of the shimming groove. When compacting the filler in the shimming groove, the operator can easily grasp the handle and apply uniform compaction force to the filler in the shimming groove through the frame and pressure blocks. This can fully compact all the filler in a shimming groove at the same time, and prevent the shimming iron sheet in the shimming groove from moving, ensuring a stable magnetic resonance shimming effect, and saving time and effort.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0008] This utility model provides a magnetic resonance shimming auxiliary device, comprising:
[0009] The frame is horizontally arranged and elongated.
[0010] A plurality of pressure blocks are disposed on the frame and distributed along the length of the frame; the lower surface of each pressure block protrudes from the lower surface of the frame and the lower surfaces of all pressure blocks are located in the same horizontal plane.
[0011] Two handles are provided on the frame and extend along the length of the frame. The two handles are symmetrically arranged based on the axis of the frame.
[0012] As a preferred technical solution, the frame is a rectangular plate.
[0013] As a preferred technical solution, a number of connecting arms are provided between the handle and the frame.
[0014] As a preferred technical solution, several of the connecting arms are distributed along the length direction of the frame.
[0015] As a preferred technical solution, the connecting arm is fixedly connected to the handle and the frame respectively by bolts.
[0016] As a preferred technical solution, the handle is located on the upper side of the frame.
[0017] As a preferred technical solution, the handle is covered with a latex or sponge layer.
[0018] As a preferred technical solution, the number of pressing blocks is set to ten.
[0019] As a preferred technical solution, the lower surface of the pressing block is square.
[0020] As a preferred technical solution, the pressure block is integrally formed with the frame or is interference-fitted.
[0021] The beneficial effects of this utility model are as follows:
[0022] The present invention has several pressure blocks distributed on the lower surface of the frame and matching the shape of the shimming groove. When compacting the filler in the shimming groove, the operator can easily grasp the handle and apply uniform compaction force to the filler in the shimming groove through the frame and the pressure blocks. This can fully compact all the filler in a shimming groove at the same time, and there will be no movement of the shimming iron sheet in the shimming groove, ensuring the stability of the magnetic resonance shimming effect, and saving time and effort.

[0029] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.
[0030] Please refer to Figures 1-5 This invention provides an embodiment of a magnetic resonance shimming auxiliary device, comprising a horizontally arranged, elongated frame 1, with several pressure blocks 2 distributed along the length of the frame 1. The lower surfaces of the pressure blocks 2 protrude from the lower surface of the frame 1, and all the lower surfaces of the pressure blocks 2 are located in the same horizontal plane. Two handles 3 are provided on the frame 1 and extend along the length of the frame 1. The two handles 3 are symmetrically arranged based on the axis of the frame 1. When compacting the filler (shimming iron sheet and filling plastic sheet) in the shimming groove, the operator can conveniently grasp the two handles 3 simultaneously and apply uniform compaction force to the filler in the shimming groove through the frame 1 and the pressure blocks 2. This can synchronously and fully compact all the filler in a shimming groove, preventing the shimming iron sheet in the shimming groove from moving, ensuring stable magnetic resonance shimming effect, and saving time and effort.
[0031] For details, please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5The shimming strip is typically long and has several shimming grooves distributed along its length. Correspondingly, the frame 1 is a rectangular plate that matches the shape of the shimming strip. Meanwhile, the shimming groove is typically a cubic groove. Correspondingly, the shape of the pressing block matches the shimming groove. The preferred material is rubber, which can simultaneously and fully compact the shimming iron sheets in all the shimming grooves. In other embodiments, the frame 1 can also be a rectangular frame, with the pressing block 2 and handle 3 able to be fixed to the frame 1 and conveniently compact the filler in the shimming groove.
[0032] In this embodiment, please refer to Figures 1-5 The handle 3 and the frame 1 are preferably fixedly connected by a number of connecting arms 4, which can ensure the stability of the connection between the handle 3 and the frame 1. Furthermore, the connecting arms 4 should be distributed along the length of the frame 1, which can effectively improve the fixing effect between the handle 3 and the frame 1. Specifically, the connecting arms 4 are preferably fixedly connected to the handle 3 and the frame 1 by bolts respectively. In other embodiments, the connecting arms 4 can also be fixedly connected to the handle 3 and the frame 1 by welding respectively.
[0033] For further details, please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 The two handles 3 should be located on the upper sides of the frame 1 so that workers can grip them at the same time, and the handles 3 will not interfere when the pressure block 2 is pressed into the uniform groove.
[0034] It should be noted that handle 3 should be covered with a latex or sponge layer to facilitate gripping by the staff and to apply sufficient pressure.
[0035] In this embodiment, please refer to Figure 4 and Figure 5 The number of pressing blocks 2 is preferably set to ten, and the total length of the ten pressing blocks 2 matches the length of the uniform groove; in other embodiments, the number of pressing blocks 2 can also be set to other values, as long as the filling material in the uniform groove can be effectively compressed.
[0036] Specifically, the lower surface of the pressure block 2 is preferably square.
[0037] Furthermore, the pressure block 2 and the frame 1 can be fixedly connected by integral molding, bolt connection or interference fit.
[0038] It should be noted that after pressing the filler into the uniforming groove using this utility model, it is also necessary to check whether there are any gaps in the uniforming groove. If there are gaps, it is necessary to continue filling the uniforming groove with plastic sheets and press it again using this utility model to ensure that there are no gaps in each uniforming groove and to prevent the uniforming iron sheet from moving.
[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
