4.8 How to capture OCT images
Depending on the features available on your device, you may be able to capture OCT images.
Select OCT and then select the OCT scan type.
FIGURE 12: OCT capture workflow
Use the following procedure for capturing OCT images. You should aim to optimize the scan (see How to
optimize OCT scan quality on the next page).
1. Select OCT to display the OCT scan types.
2. Capture an SLO image if one has
NOT
already been captured (see How to capture SLO images on
page 39).
3. Select the required OCT scan type (see Image modalities on page 24).
4. Adjust the scan position on the touch screen to the desired location.
5. Re-align the patient if required (see How to align the patient on page 37).
6. Select the live SLO image on the touch screen or press the top button on the hand control to set up
the OCT. The OCT set up auto-routines will run. Ask the patient to keep their eyes wide open at the
start of the auto-routines. During OCT set up the patient will see the alignment target, tracking scan,
and scan pattern (see
The patient's view of OCT alignment on the next page).
7. Check the SNR, center, focus and location and adjust if necessary (see Using the hand control on
page 33). Check that the SNR is 8 or greater before capturing the scan.
8. Select the live SLO image on the touch screen or press the top button on the hand control to
capture.
