The EEG cabins should be completely shielded by a continuous sheet of wire mesh of copper to avoid the picking up of noise from external electromagnetic disturbances. Such a shielding is called as:
Ans. Faraday cage
- Faraday cages are an apparatus to prevent the passage of electromagnetic waves.
- A Faraday cage is a conductive enclosure used to shield the inner space from electromagnetic interference.
- In MR imaging, this type of structure provides radiofrequency shielding to the scanning room to minimize the occurrence of interference-associated imaging artifact.
