Description

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.

Applications

The SAF8-50 Shim Amplifier RF Filter can be used in these and other applications:

  • MRI shim amplifier RF noise output filtering
  • Multi-order active shim configurations

Features and Benefits

RF Noise Filtering

Helps ensure clean and artifact-free MRI imaging.

Broad Applicability

Broadband RF attenuation characteristic spans a variety of key MR frequencies and allows OEMs to stock one cost-effective filter model.

Compact

Eight-axes of filtering allows one or two filters to easily support the numerous shim amplifiers often employed in multi-order active shim configurations.

Ease of Use

Natural convection cooling coupled with robust design ensures a long and maintenance-free product life.
