PA images of microvasculatures in small animals in vivo. (A) Wide-FOV PA image of a mouse ear. The region including a capillary bed is outlined by the white dashed box. (B) Depth-encoded PA image of a mouse eye. Circulus arteriosus major (I), iris (II), circulus arteriosus minor (III) and choroid (IV) blood vessels are highlighted by the white arrows. (C) Wide FOV PA MAP image of a mouse brain with color-encoded depths and amplitudes. Superior sagittal sinus (V) and transverse sinus (VI) are highlighted by the white arrows. FOV, field of view; MAP, maximum amplitude projection. Reproduced with permission from Reference 169.
