Optical Coherence Tomography
The Xephilio OCT-A1 Optical Coherence Tomography is Canon's Optical Coherence Tomography for the in-vivo imaging and measurement of the retina, retinal nerve fiber layer, and optic disc.
The Xephilio OCT-A1 System, which offers 1.6 μm Axial digital resolution in combination with the ability to average multiple scans, can help provide excellent image quality with detailed resolution.
The System’s integrated Scanning Laser Ophthalmoscope (SLO) contributes significantly to scan quality and ease of use. By providing real-time retinal tracking, it makes monitoring of the examination easy.
The SLO also assists with followup examinations by automatically adjusting to the same scan position as used in the previous exam. To ease comparison, the software automatically selects identical scan parameters.
With the Xephilio OCT-A1 System, you can average up to 50 cross scans* to achieve an image resolution that allows impressive detail of both the layer and the vitreous pleated structures. For optimal imaging, the System offers special scan modes for vitreous and choroid imaging in addition to a wide scan width of up to 13 mm.
The Xephilio OCT-A1 System can automatically detect and distinguish 10 layers of the retina— including Bruch’s membrane (BM)—thanks to its excellent image quality and resolution.
