(a) Doppler image without bulk phase correction, (b) Doppler image with bulk phase correction by the conventional histogram method, (c) enlarged Doppler image of a selected area within the red window in (b), (d) doppler image generated by the improved phase-resolved algorithm with more reduced artifacts than normal histogram method in (c), (e) Spectral Doppler scan trace shown on 5×5 mm OCT fundus image (140 slices × 512 A-lines), (f) the intensity and color Doppler image for one snapshot (700×256 pixels), (g) spectral Doppler wave forms that show the change of (axial) velocity and flow-volume-rate within a time span of ~7.9 s (the right grayscale bar is used to represent the volume-rate contribution for a given velocity bin) and (h) the maximum velocity envelope curve of eight cardiac cycles from which the quantitative Doppler-angle-independent flow indices were calculated.
