SELF-OCTA performance in field of view extension and high-dynamic-range flow velocity.

Caption

Fig. 2| SELF-OCTA performance in field of view extension and high-dynamic-range flow velocity. Comparison in imaging field of view and capillary details between the standard OCTA (A&C) and SELF-OCTA (B & D). Note that image A & B are acquired with the same acquisition time and in the same retinal region. C & D are enlarged view of central part (foveal avascular zone) of image A & B, respectively. Quantitative human retinal blood velocimetry in vivo. (E) SELF-OCTA images acquired simultaneously with distinct time intervals (Δt1-Δt4). Each image of time interval highlights blood velocity of specific ranges, thereby allowing blood flow velocity quantification. (F) Pseudo-color-coded retinal blood flow velocity map merged from images in (E).
