OR-PAM monitoring of the healing process of a laser-induced microvascular lesion. (a) Before laser destruction. (b) Immediately after laser destruction. (c) On each of the subsequent 12 days. The left image in each part [(a)–(c-12)] is a photograph taken by a commercial transmission-mode optical microscope; the middle one is the front view of the 3D microvascular morphology acquired by OR-PAM at 570 nm; the right one is the maximum-amplitude projection (MAP) image overlaid by the sO₂ mapping of the laser-damaged region.
