Page 20: Acquiring Images
Acquiring Images The following section shows you how to acquire images with the SPECTRALIS Ultra-Widefield Module. An introduction on how to start an examination is followed by an introduction on how to align the cSLO image. This procedure is similar regardless of the imaging modality that you select.

If your device is a SPECTRALIS OCT, press and hold the button on the joystick for approximately two seconds to activate ART Mean. ART Mean is activated. The small live images are displayed on the bottom of the acquisition window (Fig.
Page 27: Performing Angiographies
The acquired images are saved. The acquisition window closes. 5.3.5 Performing Angiographies With the SPECTRALIS, you can acquire images at a very late stage of the angiography Currently, there are only a handful of diagnoses that require very late images after 20 or 30 minutes, such as in cases of suspected optic nerve head edema, suspected tumors and other rare cases.
Page 28 To change the laser intensity to 100 % after 1 – 2 minutes, press Heidelberg Engineering recommends acquiring a movie of the early phase of the angiography. During the early phase of the angiography, single image acquisition with ART Mean might fail as the appearance of the retina changes rapidly.

Furthermore, less reflected light will be detected in cross-polarized images. The cross-polarized setting reduces the central artifact caused by lens reflections. Therefore, the cross-polarized images are darker than normal reflection images and may contain polarization effects. © Heidelberg Engineering GmbH, Article No. 230134-002 INT...
