MRI

The UNF imaging facilities include a Prisma Fit 3 Teslas MRI scanner from Siemens. This scanner is entirealy dedicated to research. It is used for research projects involving functional imaging, anatomical imaging, diffusion imaging and spectroscopy.

Visual and auditory stimuli presentation systems, as well as MR compatible response devices are also available.

Coils

  • 20 channels head/neck coil
  • 32 channels head coil
  • 64 channels head/neck coil
  • Spine coil
  • Body matrix coil
  • Wrist coil
  • Knee coil

MRI simulation room

A simulation room with a mockup of the MRI scanner is also available to researchers. The simulation room is located right next to the actual MRI room and may be used for:

  • Subject training or additional testing not requiring to be performed inside the MR scanner
  • Debugging of stimulation programs
  • Any kind of preparation required before the ME exam e.g. installation of EEG electrodes

Available equipment

  • MRI scanner mockup (Psychology Software Tools)
  • Responses pads
  • Visual and auditory stimulus presentation equipment
  • Trigger signal simulator

Data analysis

The UNF computer network is linked to the internet through the CRIUGM.

The network is used for data analysis and features about twenty calculation nodes and servers allowing every user to occupy a shared workspace as well as a personnal one. The lab is accessible 24/7 and includes 8 Linux workstations allowing users to work with the most widely used data analysis packages such as: MATLAB, SPM, FSL, AFNI, FMRISTAT or Homer. The lab is also equipped with printers, a scanner and network connections for laptops.
