Problems solved by technology

[0002] In the open cylindrical magnetic shielding cylinder in the prior art, since the magnetic shielding cylinder has an opening, its overall length and the number of layers of the magnetic shielding layer included need to be greatly increased to compensate for the attenuation of the shielding performance caused by the opening, resulting in cost and space Occupancy increases, and due to the limitation of the regular shape of the cylindrical magnetic shielding cylinder, the degree of freedom in optimization is relatively small, and the performance improvement brought by optimization is also very limited

Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some, not all, embodiments of the application. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0027] Most of the magnetic shielding tubes in the prior art adopt a closed cylindrical design or an open cylindrical design. Closed cylindrical magnetic shielding cylinder, put the object to be tested (such as the human body) into a completely closed shielding cylinder, temporarily isolated from the outside world, and has excellent shielding performance. However, the experimental forms that can be carried out using it are limited, which is not conducive to carrying out research related to near-z...

Abstract

The present application provides a method for designing a magnetic shielding cylinder, which is used to design a magnetic shielding cylinder containing multiple magnetic shielding layers, including: performing curve modeling operations based on the initial preset shape of the magnetic shielding cylinder, and constructing a magnetic shielding cylinder corresponding to The curve model; based on the shielding performance of the curve model in the simulated magnetic field, optimize the parameters of the curve model to determine the shape of the magnetic shielding cylinder. The obtained open curved magnetic shielding tube gets rid of the shape limitation of the open cylindrical magnetic shielding tube, and the shape optimization flexibility is higher in the process of designing the magnetic shielding tube, and the optimization space is further improved, so that the shape can be more fully utilized The impact on the shielding performance is changed, so that under the same shielding material usage and overall size, the open curved magnetic shielding cylinder has better shielding performance than the open cylindrical magnetic shielding cylinder. Finally, the purpose of designing a magnetic shielding cylinder with good shielding performance, low cost and high degree of optimization freedom is achieved.

Description

technical field [0001] The present application relates to the technical field of magnetic shielding, in particular to a design method and device for a magnetic shielding cylinder, a medical image acquisition system, electronic equipment, and a computer-readable storage medium. Background technique [0002] In the open cylindrical magnetic shielding cylinder in the prior art, since the magnetic shielding cylinder has an opening, its overall length and the number of layers of the magnetic shielding layer included need to be greatly increased to compensate for the attenuation of the shielding performance caused by the opening, resulting in cost and space Occupancy increases, and due to the limitation of the regular shape of the cylindrical magnetic shielding cylinder, the degree of freedom in optimization is relatively small, and the performance improvement brought by optimization is also very limited. Contents of the invention [0003] In view of this, the embodiment of the ...
