Dynamic noninvasive in vivo photoacoustic imaging by the refined UA-PAM system: (a) In vivo 3-D photoacoustic image of a human hand, the dashed line indicates the cross section monitored by real-time B-scan imaging; (b) one B-scan image corresponding to the dashed horizontal line in (a), SK, skin surface; (c) M-mode image corresponding to the dotted vertical line a in (b), showing the arterial pulsatile motion as a function of time; and (d) M-mode image of a vein corresponding to the dotted vertical line b in (b).

Noninvasive in vivo photoacoustic images acquired by the refined UA-PAM system. (a) Photograph of a Sprague Dawley rat with hair removed before photoacoustic imaging, where x represents the beamforming (B-scan) direction, y represents the mechanical scanning direction, and z represents the depth direction. The dashed rectangle indicates the imaged area. (b) Photoacoustic MAP image of the rat. The gray-scale represents relative optical absorption. (c) Photoacoustic B-scan image corresponding to the dashed horizontal line in (b), showing the depths of the blood vessels: SK, skin surface. Numbers 1 to 5 indicate corresponding blood vessels in (b) and (c). (d) Photograph of a human hand. The dashed rectangle indicates the imaged area. (e) Photoacoustic MAP image of the hand. (f) Photoacoustic B-scan image corresponding to the dashed horizontal line in (e). Numbers 1 to 4 indicate corresponding blood vessels in (e) and (f).
