Chapter 5 - About capturing an image
5 About capturing an image
The following procedure explains how to capture an image using the Capture application. The notes that
follow suggest techniques that can be used to deal with any changes that may be appropriate for an
individual patient.
You should select the appropriate Iris Category for the patient, see Detector gains on page 10.
You should capture at least two images of each eye. If necessary, you can improve the quality of the next
image, see Checking the quality of captured images on page 30.
Warning
Do not capture images when the face pad is not in place.
Do not lean on the head rest, monitor arm, monitor or keyboard tray. Ensure the
monitor arm and keyboard tray do not restrict the patient’s access to the device.
Do not start an archive task if a patient is due to be imaged in the next 30 minutes.
Some devices are supplied with a patient arm support. The patient arm support
supplied with the device is designed to support the weight of a resting arm. Do not
exceed the weight indicated on the patient arm support. When in use, ensure the
patient arm support is securely clamped to the table wing, and that it is covered
with a piece of absorbent paper.
Care should be taken adjusting the head rest or table height when the patient is
resting on the head rest.
Guidance for use on patients with Epilepsy
The device uses flashes of laser light. Some patients with epilepsy may be
sensitive to flashes of light. Caution should be exercised for patients who have a
history of reaction to camera flashes or strobe lighting.
Working with patient records
Please remember to comply with your practice procedures on personal data protection when storing
and distributing patient images.
Patient records are usually created before the image is captured, so you should not normally have to
create a new record when reviewing images. When following the instructions below, you should pay
particular attention to checking the patient record does not already exist.
You should ensure that the correct patient record is selected for each patient.
