Magnetic resonance imaging (MRI) is a relatively new imaging examination method that uses a magnetic field to identify the spatial position of the human body, excites atomic nuclei through radio wave irradiation to produce magnetic resonance phenomena, and converts them into longitudinal and transverse cross-sectional images of the human body after detector and computer processing, providing imaging basis for doctors to diagnose diseases. Due to its ability to examine almost all parts of the human body and its painless nature, magnetic resonance imaging is widely used in clinical imaging diagnosis.

The role of magnetic shielding engineering in nuclear magnetic machine room
According to GB/T 12190-2006 "Measurement Method for Shielding Efficiency of Electromagnetic Shielding Room", SJ31470-2002 "Code for Construction and Acceptance of Electromagnetic Shielding Room Engineering" and other relevant design specifications and special standards for nuclear magnetic resonance machine rooms, shielding protection engineering needs to meet the following requirements:
1. Protect the surrounding environment: avoid interference with electronic devices, ensure personnel safety, and comply with electromagnetic compatibility requirements;
2. Ensure the normal operation of equipment: improve image quality, extend equipment lifespan, and ensure equipment accuracy;
3. Meet regulatory requirements: comply with medical equipment management regulations and meet building design standards.
Key points for the construction of magnetic shielding engineering in nuclear magnetic machine room
The shielding body of the nuclear magnetic machine room needs to prevent both external electromagnetic waves from entering and internal electromagnetic waves from leaving. In order to achieve electromagnetic shielding, a closed shielding body composed of good conductors needs to be constructed.
1. Site selection: Choosing a suitable site is the primary step in constructing a magnetic shielding project for a nuclear magnetic machine room. The site should be kept away from strong magnetic field sources such as high-voltage lines, transformers, motors, etc. At the same time, the site should have good geological conditions and infrastructure to facilitate construction and equipment installation.
2. Computer room layout design: The layout of the computer room should be reasonable, taking into account the installation, maintenance, and workflow of equipment and operators. Adequate space should be reserved in the computer room for equipment cooling and ventilation. At the same time, the position and size of the doors and windows in the computer room should be designed according to the requirements of magnetic shielding to ensure that the magnetic field will not leak through the doors and windows.
3. Magnetic shielding scheme design: Select a suitable magnetic shielding scheme based on the actual situation and magnetic field strength requirements of the computer room. Common magnetic shielding schemes include ferromagnetic shielding, high permeability shielding, and electromagnetic shielding. The design scheme should consider factors such as shielding effect, cost, and construction difficulty to ensure the feasibility and economy of the scheme.
1. Shielding materials: Choosing high-performance shielding materials is the key to ensuring the quality of magnetic shielding engineering. Common shielding materials include copper plates, galvanized steel plates, and other metal materials. The selection of materials should be comprehensively considered based on factors such as magnetic field strength, frequency, and shielding requirements.
2. Insulation material: In magnetic shielding engineering, insulation material is required to isolate the shielding material from the electrical equipment inside the computer room. Insulation materials should have good insulation performance, heat resistance, and corrosion resistance to ensure the safe operation of electrical equipment.
3. Sealing material: In order to ensure the effectiveness of magnetic shielding, it is necessary to use sealing materials to seal the doors, windows, pipelines, and other parts of the computer room. The sealing material should have good sealing performance, aging resistance, and corrosion resistance to ensure that the magnetic field does not leak through the sealing area.
