Chapter 5 - About capturing an image
l
Setting the Multi-Frame Setting to capture just one image. This setting will be applied to future
sessions.
l
Pressing the hand control capture button immediately after the first image has been taken. This
method will only affect the current session.
Note
The early-phase is limited to capturing a maximum of 50 images. The session (early-phase plus any
additional images) is limited to capturing a maximum of 70 images.
Patient Management
Selecting the Allow patient procedures to be paused option lets you pause optomap® fa procedures during the
multi-frame capture phase.
Capturing Multiple Images (Angiography)
The optomap® fa procedure begins with capturing a set of optomap® plus images and then the
angiography image capture step follows. Do not inject the patient until the appropriate point in the
procedure.
Pre Capture
After completing the initial color image capture, click either Right Eye (OD) or Left Eye (OS) to start the optomap®
fa capture. The window will change to show the capture screen. You can change to the other eye after the
early-phase of the exam.
The capture window will be displayed. You can change the Fixation Level, set Eye Steering, and in some
procedures you can capture ResMax™images.
How to capture angiography images
The following procedure can be used for guidance, but you should follow your clinic's protocol if available.
Function keys have been set up for the main actions. The relevant keys are shown in the steps below.
1. Complete the preliminary checks, see Multiple Image Preliminary Checks on page 26.
2. Tell the patient what will happen, see Patient instructions on page 21.
3. If lids and lashes obscure the images to an unacceptable level try to minimize their impact, see
Minimizing lids and lashes in images on page 33.
4. Align the patient, see About capturing an image on page 19.
5. Administer the injection when the patient is aligned. Press the image capture button on the hand
control to start the timer when the injection starts, How to use the hand control on page 11.
6. Press the image capture button on the hand control again at the end of the injection being
administered to begin capturing the early-phase images.
l
The capture window displays both the time elapsed since the timer started and the number
of images already captured.
l
If necessary, increase [F3] or decrease [F4] the contrast of the images by moving the contrast
slider or pressing the function keys shown. Increase the contrast setting at the start of the
early-phase capture. This will show the dye as it enters the vessels. Decrease the contrast
setting as the dye spreads through the eye.
l
You can use the External Eye Camera view to check the patient alignment during the series. Use
the hand control buttons to make any fine adjustments to the patient's position.
l
You can press the image capture button on the hand control to stop the automatic image
capture during the early-phase. This can be useful if the patient has a reaction to the
fluorescein.
7. Once the early-phase capture has been completed, or stopped, you can capture additional images
by pressing the capture button on the hand control.
l
If required, you can capture images of the fellow eye. Click CHANGE TO [other eye] to swap to the
fellow eye. Align the patient as before. Press the image capture button on the hand control
to capture each image. You can repeat swapping between eyes until all the required
images have been captured.
l
If required, you can select an eye steering direction or the ResMax™[F2] option.
