Magnetic resonance imaging (MRI) is an image sensing method in which a large magnetic field is applied to detect a high energy and an energy release due to interaction with a hydrogen nucleus in the human body.

Such an MRI (Magnetic Resonance Imaging) is generally used in medical fields such as hospitals and is installed in a certain shield room to be used as a high-tech equipment for detecting the presence or absence of a patient's body abnormality.

Therefore, the MRI-shielded room is formed as a ferromagnetic region inside the operation, which is the key to maintaining the complete indoor and outdoor shielding.

Meanwhile, in the conventional MRI electromagnetic shielding room (RF SHIELD ROOM), vibrations and noise generated in the MRI operation are propagated to the surroundings, causing severe noise pollution. Therefore, a dustproof and sound insulation structure is required.

In addition, the bottom portion of the conventional electromagnetic wave shielding chamber is vulnerable to water and moisture, causing deformation of the bottom plate, which is a cause of frequent maintenance which is directly related to the life of the equipment.
