Video Recording (ex. facial expression)

Setting up the camera in the MRI imaging room

Usually, a lens is installed for eye tracking measurements.
Adjust the lens according to the conditions of the object to be recorded (facial expression, hand, body, etc.).

〇 Six types of lenses (wide-angle (2.9mm)->telephoto (16mm))
〇Monochrome

Take off the camera cap.

Place the camera on the camera pedestal with blue arm.

Be careful not to lose screws.

Place the camera pedestal with arm in the mirrored arch.

A head coil with an open face is placed on the MRI bunk.
Once the subject is guided to the bed, an arch with a camera is attached.

The position of the camera is adjusted to obtain the desired angle of view.
*At this time, be careful that the camera does not touch the gantry when the bunk is placed in the gantry. If the camera is fixed higher than the arch, it will hit the gantry.

Setting in the operation room

The video capture device and cables are contained in a cardboard box under the stimulus presentation PC in the MRI operation room.

The black cable connects the black cord to the gray cable (BNC cable) under the desk.

The blue cable connects to the PC.

It will be recognized as a normal USB webcam and will record.
