About “Peripheral” photography
This section describes how to switch the light position of the xation target and how to guide the patient's
xation when “Peripheral” photography is selected.
Go to [Settings\Internal Fixation Target] to specify a photography sequence for a part to be photographed.
When “Peripheral” is selected, the xation targets turn on to guide you through the specied sequence.
The xation target applicable for the rst part to be photographed is lit immediately after selecting “Pe-
ripheral”. The screen shows the guiding direction for the patient's xation; guide the patient in the direc-
tion exactly as indicated.
Example:
1) To photograph the part No.1, “Center” is indicated on the LCD monitor.
You would say to the patient, “Please look at the luminous dot in the center.”
2) To photograph the part No.2, “Up” is indicated on the LCD monitor.
You would say to the patient, “Please look at the luminous dot above the center.”
3) To photograph the part No.3, “Left up” is indicated on the LCD monitor.
You would say to the patient, “Please look at the luminous dot on upper left.”
Once an image is photographed, the fixation target changes according to the next part to be photo-
graphed. Continue to guide the patient's xation and photograph images.

If the currently set photography sequence includes parts unnecessary to be photographed or if you want
to recapture an already-photographed part, you may use the arrow buttons (“NEXT button” and “BACK
button”) on the LCD monitor to change the sequence.
Press “NEXT button” to switch to the xation target for the part to be photographed next.
Press “BACK button” to switch to the xation target for the part previously photographed.

The internal xation target may not be visible to the patient immediately after switching the position.
First, guide the patient's xation to the general area indicated on your monitor; then, instruct the pa-
tient to look at the luminous dot as it becomes visible during the alignment process.
