Functional MRI Core Facility - Major Equipment Descriptions

3T-1
Hardware characteristics of 3T-1 include:
  • Actively shielded magnet with high homogeneity (< .5 ppm rms @ 40 cm DSV) for homogeneity sensitive sequences (Spectroscopy and SS-EPI)
  • RF platform which includes phased array compatibility
  • Coils from GE and third party coil manufacturers
  • Gradients with peak amplitude of 40 mT/m
  • Slew rate equal to 150 mT/m/msec
  • Maximum FOV of 40 cm

NIH 4.7 Tesla Vertical Magnet System
for fMRI in non-human primates

This non-human primate MRI scanner is made by Bruker, and is being installed on the NIH campus.

The Bruker BioSpin MRI BioSpec® vertical bore magnets have been specially designed for fMRI investigations in primates. The system installed at NIH is an actively shielded 4.7T magnet. The 60cm in-diameter magnet bore size allows a 28cm in-diameter free access space for imaging.

The BioSpec® Vertical uses the same Bruker AVANCE™ digital spectrometer, workstation, and operating environment as the regular Bruker BioSpec®. The operating software is the Paravision System Software.

For better reproducibility in positioning, the system is equipped with a "sample positioning lift", which will be inserted from the base of the magnet.
