Tracking microscopic progression/regression
By design, the rtx1 delivers images that are free from motion distortion. Building on this advantage, its software enables capturing the same retinal region through different visits, and automatically aligns follow-up images. This allows tracking minute changes in a group of cells, a vessel section, or a lesion over time.
