Problems solved by technology

But its disadvantage is that due to the strong magnetic force, it is difficult to move and install the magnetized permanent magnet cylinder on the pole plate, and it is especially difficult to install and position the permanent magnet cylinder near the edge of the pole plate and near the frame.
Although most manufacturers tend to adopt a similar permanent magnet column installation method, there is a problem that the permanent magnet column is difficult to install due to the magnetic force, especially at the edge of the pole plate.

Embodiment Construction

[0026] According to an embodiment of the present invention, there is provided a method for installing a permanent magnet magnet in a permanent magnetic field generating device of an open C-type magnetic resonance imaging device, in which an additional board unique to the present invention is used, such as figure 2 with 3Shown. However, these embodiments are not restrictive, and the present invention is not limited to magnetic resonance magnets, nor is it limited to open C-type permanent magnet structures.

[0027] Such as figure 2 As shown, the upper and lower pressing plates 2, 21, the upper and lower pole plates 3, 31, and the Ross rings 4, 41 of the magnetic resonance imaging equipment have been installed, and the permanent magnetic field generator 10 is about to be installed. Prior to this, a separate additional plate 6 should be installed on the periphery of the above-mentioned pressing plates 2, 21 and the above-mentioned pole plates 3, 31 in advance. The additional board ...

Abstract

The present invention proposes permanent magnetic column installing method and tool for permanent magnetic field generator in, such as, magnetic resonant imaging equipment. The installation method includes the following steps: sliding permanent magnetic column via an additional board installed around the plate electrode to the surface of the plate electrode; painting adhesive to at least one side of the permanent magnetic column; adhering the permanent magnetic column to one other permanent magnetic column installed on the plate electrode in advance; and repeating the foregoing steps until finishing the installation of the permanent magnetic field generator. The present invention has the advantages of flexible operation and enlarged operation area.

Description

(1) Technical field [0001] The present invention relates to a method for installing permanent magnetic materials in a permanent magnetic field generating device and a conveying tool, in particular to a method for installing permanent magnetic field generating devices in a magnetic resonance imaging equipment (MRI) and tools used, In the manufacturing process of magnetic resonance imaging equipment, permanent magnet cylinders are assembled on the pole plates. (2) Background technology [0002] In measurement and imaging technology, magnetic fields are widely used, for example, various types of magnetic resonance imaging devices, in which permanent magnetic fields generated by permanent magnetic materials are used. Take the open C-type permanent magnet magnetic resonance imaging equipment as an example, its main mechanical structure is as figure 1 As shown, an open magnetic resonance imaging equipment includes: a C-shaped frame 1 as a magnetic circuit; an upper pressing plate 2 an...
