Examination Sets and Scan Modes
To capture images using optical coherence tomography (OCT), first select an
examination set. Multiple scan modes (combinations of scan direction, area, and other
conditions for capturing images) are registered in examination sets. You can select an
examination set to capture images according to certain diseases and the anatomy being
examined. Check the content of the examination sets beforehand and select one that is
appropriate for image capture.
