3.2.7 How to capture SLO angiography images
The device supports the capture of angiography images.
CAUTION
When angiography images are being captured additional space will be required to allow
the injection of the dye and for other individuals involved in the procedure. These
individuals could include medical staff or patient helper.
Do not inject the patient until the appropriate point in the angiography procedure.
Selecting Angiography will allow the manual capture of FA or ICG images. In Angiography mode, the FA or
ICG timers can be configured to run separately or as a single combined timer. A timer is started by either
selecting the timer or when the initial image captured. The injection should be administered when the scan
head is aligned. If a timer is started accidentally you can reset it by selecting the timer and selecting
Reset .
You may manually switch between FA and ICG .
Note
l
You can manually switch between FA and ICG images when both image modalities are being
captured.
l
Auto-capture is available for angiography images, and ensures automatic capture of images when
the scan head is in the correct position relative to the patient.
l
You can select non-angiography image modalities, eye steering and stereo options while performing
an angiography session.
3.2.7.1 Control contrast
You can adjust the contrast for the next image to be captured.
Manually adjust the image contrast by pushing the contrast control to the left or right or by selecting the
desired position on the control.
Depending on the features available on your device you may be able to use the auto contrast. Manually
adjusting the contrast turns auto contrast off. You can switch between
Manual and Auto contrast control
modes.
The contrast is set separately for opto map fa and opto map icg images. When you change between opto map
fa and opto map icg , the device uses the most recent contrast settings for the selected image modalities.
