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.
