Very-low-field MRI
The Very-Low-Field MRI Facility is located inside the Biomagnetism section of ITAB.
This facility started during the MEGMRI project 2008-2012, coordinator Ilmoniemi;
its starting was also supported by PRIN 2010-2012.
During these projects a MEG-compatible prototype for VLF-MRI, based on a hybrid scheme, was implemented
Equipment:
- shielded room with 3 m-metal and 1 aluminum layers, RF-filtered throughputs
- 1 cryostats with curved bottom (CTF) and equipment for vacuum pumping and cryogenics
- A/D conversion and acquisition unit for SQUID signals
- Driving and readout electronics for VLF-MRI
- VLF-MRI console with 4 input channels and 1 output channel, driven by a dedicated computer; it is possible to obtain echos, 1D, 2D and 3D images using the spin-echo sequence
- MRI preprocessing unit
- Electronics lab
VLF-MRI – which measures can be done
- Applications of VLF-MRI
With the room-temperature detection using the volume coil, 3D-images of phantoms or small animals are possible within a reasonable recording time
- Academic training/research to improve the superconducting detection
Using the surface coil, 2D-images of phantoms or small animals are possible, although at longer times. Alternate schemes could be adapted to the existing set-up
