In the multi-isoplanatic patch phase aberration correction technique, unfocused waves are steered off-axis to investigate several unique propagation paths through the nearfield skull aberrator, indicated by differently colored rays. Each color corresponds to a subset of image lines within a 3D volume. In this work, five isoplanatic patches are estimated and corrected. The central update regions (red) is 32° × 32°; outer regions are 16° × 32° or 32° × 16°.
