Pathway Technical Reference Manual
Proprietary 149 of 190
15. Appendix D – fMRI Conditional PATHWAY
PATHWAY fMRI Thermode and accessories are defined and marked as MR
Conditional equipment according to the ASTM F2503–08.
PATHWAY Cart and MR filters are defined and marked as MR Unsafe
equipment according to the ASTM F2503–08.
WARNING:
Make sure that the Thermode is unblemished in order to prevent potential
harm to the test subject.
The fMRI PATHWAY system was tested in the following MR environments:
Field Strength: 3T; Max. Spatial gradient: 72 mT/m
Max. dB/dt: 346 T/m/s; RF Fields: max. power 35KW pep;
TX bandwidth: 800kHz; RX bandwidth: 500Hz-1MHz; maximal RF field
strength: 24,7 µT CP
SAR: whole body 4 W/kg, head 3.2 W/Kg
The fMRI PATHWAY system was tested in the following MR Sequences:
1. Fast Spin Echo (FSE) T1
2. Fast Spin Echo (FSE) T2
3. Spoiled Gradient Echo (SPGR)
4. Echo Planer Imaging (EPI) bold (fMRI)
5. Gradient Echo
