The magnetic resonance system is a high-precision diagnostic equipment, which has higher requirements for the installation environment. The NMR signal is a very weak signal, which is easily affected by external interference. The interference mentioned here is mainly vibration interference.
Vibration interference refers to any type of vibration transmitted from the structure of the building to the MRI scanner, and may come from many external sources. It can be other machines in the building, usually elevators in hospitals, other types of scanning equipment, etc., as well as electric motors, vehicles/trains/subway, etc. passing near the building.
The MRI system has been in China for 40 years. With the continuous advancement of computer technology, MRI has also been developing in the direction of high field strength and high gradient, and other large-scale medical equipment in various hospitals are constantly being added and updated. , The construction of various functional buildings in the hospital, the appearance of the above factors makes the MRI equipment room narrow, and at the same time, it is interfered by various other large-scale medical equipment, subways, substations, radio signals and other factors. Based on the influence of the above factors, it is extremely important to effectively evaluate the interference situation of the nuclear magnetic resonance site and take targeted interference protection measures.
CSJ-PAD is a site vibration interference solution system developed by our company. By installing a shock absorption device on MRI equipment, it can accurately and effectively detect environmental electromagnetic field interference and vibration interference, give accurate judgments, and provide effective solutions.
For example, it can provide effective shock absorption and shielding to the vibration interference caused by large-scale sports equipment such as subways, trains, and trams.
