OCT Optovue Avanti Widefield

Visionix Optovue Avanti Widefield OCT: Advanced Retinal Imaging with ANGIOVUE HD and PAR Technology

The Visionix Optovue Avanti Widefield OCT represents the pinnacle of ocular imaging technology, offering comprehensive views from the cornea to the choroid. Equipped with exclusive technology, this device will revolutionize your approach to the diagnosis and management of ocular diseases. With enhanced high-definition imaging of the vitreous and choroid, the Avanti Widefield OCT is capable of providing detailed visualizations with an axial resolution of 5 µm and a transverse resolution of 15 µm. Through its 12 mm widefield scan and enhanced depth imaging mode, eye care professionals can conduct precise quantitative analyses of ocular structures, aiding in faster and more accurate diagnoses.

The Avanti's 3D Widefield En Face Imaging technology allows for three-dimensional visualization of the retina and the study of individual retinal layers with en face imaging. This functionality facilitates the rapid identification of structural abnormalities through the Widefield En Face Quad Image report, which offers a comprehensive view of the retinal layers, enabling a more detailed assessment of ocular conditions.

Additionally, the Avanti can be complemented with AngioVue OCT Angiography, which provides non-invasive vascular imaging of the retinal and optic disc vessels. This addition to the Avanti system allows eye care professionals to observe the ocular microvasculature in unprecedented detail, enhancing the diagnostic capability for retinal vascular diseases.

AngioVue HD further elevates the standard of image quality, offering an OCTA density of 400x400 compared to the traditional 304x304 density. This increase in density provides detailed views of fine vessels extending beyond the central 3x3 mm region of the macula, delivering the highest resolution for large format images. With AngioVue HD, eye care professionals have at their disposal a powerful tool for obtaining detailed and precise images of ocular vascular structures, improving the detection and monitoring of ocular diseases.

The Visionix Optovue Avanti Widefield OCT also stands out for its Angiovue HD Automatic Montage feature, which offers a 10x6 mm field of view with exceptional resolution of the retinal vasculature in the macula and optic disc. This feature allows eye care professionals to obtain detailed images of wide areas of the retina, facilitating comprehensive analysis of vascular structures.

Another significant innovation is the Angiovue Projection Artifact Removal (PAR), which utilizes 3D projection artifact removal to reduce artifacts in all posterior layers of the retina. The PAR performs a vessel-by-vessel analysis to remove artifact vessels while maintaining the authentic vasculature. This precision is essential for accurate interpretation and quantification of the images, ensuring that eye care professionals can trust the quality of the obtained data.

The PAR 3D also reduces overcorrection, a common problem in traditional projection artifact removal algorithms. Unlike these methods, the PAR 3D maintains signal strength to better display the actual vasculature, providing a more faithful and detailed image of vascular structures, which is crucial for precise diagnoses.

The DualTrac Motion Correction technology combines real-time tracking, a high-speed infrared camera (30 frames per second), and proprietary post-processing to enable true three-dimensional correction of distortions in all directions. The result is ultra-precise motion correction, resulting in superior image quality, essential for detailed and reliable evaluations.

The Angioanalytics feature of the Avanti allows for the measurement of the Flow Area by delineating a region for vessel detection. The extracted Flow Area measurement is based on the Outer Retina layer (OPL ~ BRM), providing crucial quantitative data for the assessment of retinal blood circulation.

Additionally, vessel density mapping measures the density of vessels in the superficial and deep retinal plexuses as well as the peripapillary radial capillary layer of the optic disc. This detailed mapping is vital for better understanding the vascular health of the retina and identifying potential anomalies, enhancing the ability to diagnose and monitor eye diseases.
