Page 10: Overview
1 Introduction Overview Optical Coherence Tomography (OCT) The Canon Optical Coherence Tomography (referred to as “OCT” in this manual) takes digital photographic images of retinal form and tomogram images of patient’s eyes non- invasively with full automatic alignment. Full automatic operations can decrease examination time and automatic tracking enables the OCT to take images with high reproducibility.
Page 11: Indications For Use
It is intended for use as an aid in the diagnosis and management of posterior segment diseases. Important • The Canon OCT is not intended to be used as the sole diagnostic instrument for disease. A qualified doctor is responsible for the definitive diagnosis referring to other analysis results with other instruments.

Page 265: Working Principle
Appendix Working Principle The retinal tomogram is obtained by using the optical interference. Near-infrared light, which is emitted by the super luminescence diode (SLD), is separated by the beam splitter. One separated light is guided to the reference mirror and is reflected by it. Then, the light returns to the beam splitter.
