System Overview
Figure 7 - ETT Gustometer 2 system overview with left - device (non-MR compatible) and right - applicator (mouthpiece) on
subject (MR compatible))
The general system setup is shown in Figure 7. It is advisable to first setup the components unrelated to
the subject and test everything is connected before setting up a research subject on the patient table.
Warning -
the main device is not MR compatible.
Only the following components are MR compatible:
•
Mouthpiece / tastant applicator
•
RF coil mount
•
Swallow / respiratory sensor bladders
•
Long distance PTFE connection tubing
All other components cannot be brought inside the magnetic field.
Start by setting up the ETT Gustometer 2 outside the experimentation room. Even for EEG experiments
it might be advisable to maintain a wall separation between subject and device. Each pump has a slightly
different pitch, which might inform the subject which is the currently active stimulus.
Connect the power supply cable and power the Gustometer up by pressing the power button on the
front panel. Connect a USB flash drive to the
DATA
port. Optionally connect the various triggers and
sensor that may be provided with your system. The ETT Gustometer 2 can easily be triggered with a TTL
pulse from and other device via
Trigger in
BNC port. The sent pulse should be at least 1 ms long. To
initialize the trigger handler, load a paradigm and press
Trig Start
to wait for a trigger. As soon as the
trigger is visible to the device the paradigm starts.
