9.4T MRI

The 9.4T Bruker Biospec MRI system (30 cm bore) is designed for hardware-intensive experiments such as high resolution imaging, functional imaging, and diffusion imaging. The large gradient set has an internal diameter of 20 cm and a gradient strength of 200 mT/m, and is suitable for imaging larger rodents such as rabbits and guinea pigs.  The gradient insert with 12 cm diameter and a gradient strength of 450 mT/m is suitable for imaging mice and rats.  An AutoPac laser positioning system enables rapid and precise sample positioning.  The system has four receive channels for parallel imaging, and four transmit channels, including one for X-nuclei.

RF coils available for this system include:

Volume coils

  • 23mm ID, quadrature coil designed for mouse brain
  • 25 mm ID, quadrature coil designed for small phantoms
  • 40 mm ID, quadrature coil designed for mouse body and rat head
  • 72 mm ID, linear coil designed for rat body, tunable to 1H or 19F
  • 72mm ID, linear coil designed for rat body; can be used as transmit only coil for receive only surface coils. Soon to be upgraded to a quadrature version!
  • 154 mm ID, designed for guinea pig and small rabbits

Surface coils (all 4 channel phased array receive only; used with 72 mm ID transmit only volume coil)

  • Mouse brain
  • Rat brain
  • Rat cardiac
