EMIS has announced the availability of the MF420-2CF-M MRI filter, engineered to suppress electromagnetic interference (EMI) and radio-frequency interference (RFI) in Magnetic Resonance Imaging environments.
The solution is designed to protect highly sensitive MRI systems from external noise, ensuring reliable imaging performance and regulatory compliance.
Addressing the challenges of MRI environments
MRI systems operate using extremely low-level RF signals within strong magnetic fields, making them highly susceptible to interference.
Even minor EMI contamination can:
- Degrade signal-to-noise ratio
- Introduce imaging artifacts
- Compromise diagnostic accuracy
- Lead to compliance issues
Additionally, cables entering MRI rooms can act as antennas, allowing unwanted signals to penetrate shielded environments.
Wideband suppression up to 10 GHz
The MF420-2CF-M filter provides high attenuation across a wide frequency range of up to 10 GHz, helping to maintain clean signal conditions within MRI suites.
Typical installation points include:
