About the MXW Series
The MXW series shim power amplifier enables shimming of MRI magnets under static and dynamic shim updating and real time shimming on multiple slices, voxels or regions of interest with simultaneous compensation of shim induced eddy currents.

The Challenge:

To provide a stable current source with high output compliance for control of multiple shim channels in a modern MRI system.

To ensure stable operation in the presence of large voltages induced in the shim coils.

To have flexible digital and analog control from the MRI console for static and dynamic operation.
