GAF-DSRS Gradient Amplifier RF Filter

The GAF-DSRS Gradient Amplifier RF Filter from Performance Controls, Inc. (PCI) provides RF noise filtering between a gradient amplifier and MRI system gradient coils. The filter is designed to be wall-mounted to a penetration panel. The filter reliably attenuates unwanted RF noise from the gradient amplifier outputs as they pass into the MRI magnet room.

The single-axis (two channels) design provides a lightweight, cost-effective solution for flexibly deploying multiple filters in support of multi-axes system requirements.

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 MR systems based on the attenuation requirements.

The filter is designed to operate in a controlled equipment room environment with controlled temperature and humidity.
