MAGNETIC FIELD MAPPING 
MRI MAGNETS - FMU-MRI

The FMU-1200 is a state-of-the-art, computer-controlled ¹H NMR based mapping system for the analysis of inhomogeneities in NMR magnets.

The FMU-1200 provides an easy and fast method for automated convergence of super-conducting and room temperature shims, a mandatory requirement for enhanced spectral quality in advanced NMR applications.

It also provides efficient magnet qualification, staging, evaluation of magnet drift and design and evaluation of ferromagnetic shimming.

At the heart of the FMU-1200 is a heli-cylindrical probe manipulator, designed for single sample operation. The system acquires and analyzes data for axial and radial components in about 8 minutes.

The single probe head with variable operating frequency provides flexibility, reduces the relative cost of the system and saves time and labor spent on change and calibration of probes.

CUSTOMIZED CONFIGURATIONS

The FMU-1200 Magnetic Field Mapping Unit can be configured to operate with specific NMR consoles. 

RRI has been supplying magnetic field mappers for magnet manufacturers, magnet staging companies, suppliers of NMR systems and research institutions for the last 10 years.

Each customer receives an intensive training course for the operators that can be repeated periodically, for updating and training of new operators.

Extended support and upgrades are made available through Technical Support contracts. The system is protected by a one-year warranty on parts and labor and includes unlimited telephone support.
