Embodiment Construction

[0024] The present invention is further described in detail below through specific embodiments, but the present invention is not limited thereto.

[0025] The present invention is achieved by changing the structure of the prior art MRI system, that is, making the electrical cabinet containing the electrical equipment of the MRI system and the magnetic field generating equipment generating the magnetic field close to each other, for example, connected by traditional mechanical connecting means (such as bolts, etc.) , so that the heat generated by the electrical equipment in the electrical cabinet can be used to heat the permanent magnet, so that the MRI system does not need to set up a special cooling device for the electrical cabinet, nor does it need to set a heater for the permanent magnet, so as to make full use of energy and simplify the system structure. At the same time, the MRI system has a compact structure, simple installation and cost saving.

[0026] In the above-me...

Abstract

The invention relates to a magnetic resonance imaging system and a method for stabilizing the temperature of a main magnet in the magnetic resonance imaging system. By mutually approaching an electric cabinet and magnetic field generating equipment, the heat generated by the electric cabinet can be used for heating the main magnet, and meanwhile, the electric cabinet can be cooled without mounting a heater on the main magnet and specially mounting a cooling system on the electric cabinet. The magnetic resonance imaging system has simplified structure and miniature design, energy saving, cost reduction and reliability increase. In addition, the invention is easy for application.

Description

technical field [0001] The present invention relates to Magnetic Resonance Imaging (MRI) technology, and in particular to the heating of magnets and the cooling of electrical equipment. Background technique [0002] An MRI system is a system that obtains magnetic resonance signals of a human body under a magnetic field according to the principle of nuclear magnetic resonance and reconstructs images based on the magnetic resonance signals. An MRI system typically includes a main magnet (which can generally be a permanent magnet, an electromagnet, or a superconducting magnet, this patent discusses the case where the main magnet is a permanent magnet), gradient coils, electrical parts, radio frequency (RF) coils, and these parts are responsible for MR signal generation, detection and encoding; MRI system also includes analog converters, computers, disks and tape drives, etc., these parts are used for data processing, image reconstruction, display and storage. The main magnet i...
