[Optimize]

Remind the Patient they can blink as normal as there is an Auto Tracker, but to keep fixated
on the fixation target. You will see the Scan Position move down as it scans.

If scanning takes too long, press the trigger on the joystick again to cancel Auto Tracking.
This will complete the scanning without tracking. The Patient must then be asked not to blink
to avoid artefact.

Images will be saved automatically onto Imagenet 6 software.
Scan Position
Blinking or eye movement prevents
scanning. When scanning stops, a red

when the alignment position is OK. It
completes the scan until the end.
