Rat Array MRI CryoProbe from Bruker BioSpin

Rat Array MRI CryoProbe from Bruker BioSpin

Advanced MRI coil technology delivers highest sensitivity in rat brain in vivo imaging

The rat array MRI CryoProbe™ for in vivo neuroimaging delivers unparalleled access to rat brain microstructure and biochemistry, previously unresolvable in in vivo imaging of the rat. Thanks to very low temperature, closed-cycle cooled RF coils and preamplifiers, this unique MRI CryoProbe delivers an increase in signal-to-noise ratio (SNR) of up to a factor of 2.4 over equivalent room-teperature RF-coils. The sensitivity increase allows researchers to reduce imaging times by a factor of 5, or to increase spatial resolution.


  • Up to 2.4 factor increase in SNR
  • Factor 5 reduction in imaging times
  • Seamless integration with ParaVision® 6
  • Automatic hardware recognition
  • Automatic tuning and matching
  • Available at 400 MHz (9.4 T)

Technical Details

Based on a 2x2 array cryogenically-cooled RF coil that combines the high sensitivity of Bruker‘s CryoProbe technology with parallel acquisition capabilities the MRI CryoProbe delivers maximum imaging speed and highest spatial resolution at 9.4 Tesla.

The probe seamlessly integrates with Bruker’s powerful ParaVision 6 software, opening up a vast world of imaging protocols and experiment parameters to any researcher. With hardware recognition, and automatic tuning and matching for optimum performance and productivity, the rat MRI CryoProbe is also very suited to routine imaging environments.

The corresponding CryoPlatform supplies cold Helium gas via a closed loop circuit, eliminating any need for handling of cryogens.  The patented temperature shielding technology guarantees safe operation and optimal performance.

Bruker is the pioneer and world leader in the development of cryogenically-cooled probes for high-resolution NMR, with over 1,300 units sold in the last decade. That expertise and foresight has been transferred successfully to the MRI CryoProbeTM, and already over the last few years, around 60 of these peerless probes have been installed worldwide.
