SAF8-50 Shim Amplifier RF Filter
The SAF8-50 Shim Amplifier Filter from Performance Controls, Inc. (PCI) provides RF noise filtering between eight axes of shim amplifiers and their associated MRI shim coils. The filter reliably attenuates unwanted RF noise from the shim amplifier outputs as they pass into the MRI magnet room. The filter attenuates broadband RF with special consideration given to the MR frequencies associated with 0.5T, 0.7T, 1.2T, 1.5T and 3T MRI systems. The filter may apply to other MRI systems based on attenuation requirements.
The filter is designed to be wall-mounted to a penetration panel and is designed to operate in a controlled equipment room environment.
