fMRI Thermode

Q-sense fMRI Thermode and accessories are defined and marked as MR
Conditional equipment according to the ASTM F2503–08.

Q-sense 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.

WARNING:
To avoid the risk of electric shock, this equipment must only be connected
to a supply mains with protective earth.

The fMRI Q-sense system was tested in the following MR environments:
Field Strength: 3T and 7T; 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 Q-sense system was tested in the following MR Sequences:
1.

Echo Planer Imaging (EPI) bold (fMRI)

2.

rf_noise and rf_noise spectrum electromagnetic noise interference
(Siemens protocol)

26.1.1

Q-sense system configuration in fMRI mode:

The fMRI Q-sense system includes the following components:


