Customizable RGB Color Channels

Users can enhance visualization by selecting the R (Red), G (Green), or B (Blue) color channels, allowing targeted observation of lesions in the most suitable color spectrum for a more precise evaluation.

The Angio Enhancement suite of the HOCT-1F (80) increases performance and reliability by combining scan speed increments based on location with real-time retinal tracking via a 30 fps infrared (IR) camera. Image quality is elevated through slab-based vascular signal contrast with foveal reflex suppression, along with post-acquisition B-scan registration that restores interrupted vessels. CNV (choroidal neovascularization) visualization benefits from an improved despeckling process that highlights only true neovascular structures. Robust noise controls eliminate motion artifacts, suppress horizontal banding noise, and remove the ghosting effect, while PAR (projection artifact removal) eliminates superficial vessel shadows and more sharply defines the outer retina. Finally, refined retinal layer segmentation enables more precise analysis of regions in OCTA, reinforcing diagnostic confidence.

Real-Time Retinal Tracking

The HOCT-1F (80) offers precise visualization of the retinal microvasculature through real-time retinal tracking with a 30 fps IR camera that corrects eye movement during acquisition.

By reducing motion blur and suppressing banding artifacts, it preserves vascular continuity and sharp capillary borders, producing stable and faithful OCTA images even in the presence of small fixation movements or blinks, allowing clearer data to be captured with fewer repetitions.

Enhanced Signal Contrast in CNV

The HOCT-1F (80) improves the visibility of choroidal neovascularization (CNV) in the outer retina by optimizing signal processing within the selected OCTA slab, suppressing foveal specular reflections and reducing noise.

The result is greater vessel-to-background contrast with preserved microvascular continuity, a cleaner representation of fine capillaries, and more reliable delineation of CNV networks, enhancing detection, boundary assessment, and comparison in clinical follow-up.

Motion Artifact Removal

The HOCT-1F (80) minimizes motion-related artifacts in OCTA by correcting ocular micro-movements during acquisition and applying a dedicated “stripe noise” reduction algorithm that suppresses horizontal banding.

The result is cleaner slabs with preserved vascular continuity, sharper capillary edges, and reduced background noise, providing more readable images and reducing the need for repeated scans.

Projection Artifact Removal (PAR)

The HOCT-1F (80) uses PAR to suppress shadow-like projections from the superficial vascular plexus that contaminate deeper OCTA slabs.

By eliminating these projection artifacts, the system preserves genuine flow signals in the outer retina, improves vessel-to-background contrast, and maintains microvascular continuity.

The result is a cleaner, more faithful visualization of structures such as CNV, with sharper borders and fewer false positives, supporting more accurate interpretation and more reliable longitudinal quantification.

Enhanced Retinal Layer Segmentation (RPEDC)

The HOCT-1F (80) delivers more precise layer segmentation, with special improvements in the RPE/Bruch’s membrane complex. Its refined algorithm reliably tracks the RPEDC boundary, even in irregular morphologies, reducing manual corrections and increasing reproducibility.

By clearly separating the outer retinal layers, it enables better visualization of sub-RPE structures, improved detection and delineation of drusen/PED, and more reliable thickness and en-face maps.

The result is consistent slab selection and greater diagnostic confidence in the evaluation of subtle RPEDC changes over time.
